Cardview Rounded Corners are not showing up in Screenshot?

Cardview Rounded Corners are not showing up in Screenshot? - java

I'm trying take screenshot of a cardview which is in a DialogFragment. When I take a screenshot via Code. Top rounded corners are not showing but the bottom rounded corners are showing correctly. I saw these issues mentioned in the below Questions...
Cardview loses its radius when taken a screenshot programmatically
Using PixelCopy to copy a scaled View within a DialogFragment
As per the above question, I tested the same layout & code in a Fragment class. Then the rounded corners are showing up correctly...

Try the following as a replacement for ViewImage.kt in the referenced project. The main change is to pass in the view's window rather than an Activity. Dialogs have their own windows and don't share a window with activities.

I Noticed that you are trying to take a screenshot from 'mainRelative' which does not exist in your xml, I think you should use the id of 'cardView' or 'mainlinear' based on your requirements.

The Answer given by #Cheticamp is right
Lets Convert it into java
public class ScreenshotTaker {
private static final String TAG = ScreenshotTaker.class.getSimpleName();
/**
* Takes screenshot of given view and saves it in external storage
* #param view outer most ViewGroup that you want a screenshot of
* #return File object of saved screenshot in storage
*/
public static File captureScreenshot(View view) {
Bitmap bitmap = Bitmap.createBitmap(view.getWidth(),
view.getHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
view.draw(canvas);
return saveBitmap(view.getContext(),bitmap);
}
public interface screenshotFile{
void onComplete(File file);
}
public static void getScreenShotFromView(View view, Window window, screenshotFile callback ) {
Bitmap bitmap;
// PixelCopy is available since API 24 but doesn't seem to work 100% until API 29.
// The build version statement can be adjusted according to how well PixelCopy
// works in your environment before "P".
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
int[] locationOfView = new int[2];
view.getLocationInWindow(locationOfView);
Rect rect = new Rect(locationOfView[0], locationOfView[1],
locationOfView[0] + view.getWidth(), locationOfView[1] + view.getHeight());
bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), Bitmap.Config.ARGB_8888);
try {
PixelCopy.request(window, rect, bitmap, new PixelCopy.OnPixelCopyFinishedListener() {
#Override
public void onPixelCopyFinished(int copyResult) {
if (copyResult == PixelCopy.SUCCESS) {
callback.onComplete(saveBitmap(view.getContext(),bitmap));

Android Mapbox NavigationView is not loading map

It would be great if you can help me to fix this weird issue.

Can you try to set the content theme
super.onCreate(savedInstanceState)
setTheme(R.style.Theme_AppCompat_Light_NoActionBar);
before setting the contentView?
Also where did you set the style of NavigationView? You can do that in the layout XML file:
<com.mapbox.services.android.navigation.ui.v5.NavigationView
android:id="#+id/navigationView"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:navigationDarkTheme="#style/CustomNavigationView"
app:navigationLightTheme="#style/CustomNavigationView"
app:navigationViewMapStyle="mapbox://styles/StyleURL"/>
Please use your custom styleURL.
Please let me know if it helped!

Solution in Kotlin
For more information
This issue has been resolved here Can’t start turn-by-turn navigation within custom NavigationViewActivity/NavigationViewFragment #1524
First I updated the SDK version from 0.13.0 to 0.23.0
implementation 'com.mapbox.mapboxsdk:mapbox-android-navigation-ui:0.23.0'
The dependency will transitively bring in the Maps SDK and the core navigation libraries. This helps prevents conflicts.
In project root build.gradle don't forget to add
maven { url 'https://mapbox.bintray.com/mapbox' }
in fragment_navigation.xml

Save a MPAndroidChart chart to an Image without displaying it on an activity

I want to generate a PDF, but first I need to create an image from a LineChart (MPAndroidChart library) without displaying it in an activity.
I've followed this tutorial http://android-crap.blogspot.com/2013/02/create-bitmap-from-layoutview.html, and I've modified the code to my own requirement:
private void createLineChart(double frequency) {
LayoutInflater inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout view = new RelativeLayout(activity);
inflater.inflate(R.layout.line_chart_layout, view, true);
LineChart lc = view.findViewById(R.id.lncMain);
lc.setData(createLineData(frequency));
lc.invalidate();
view.setLayoutParams(new LinearLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT));
view.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED),
View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
Bitmap b = Bitmap.createBitmap(view.getMeasuredWidth(), view.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
view.layout(view.getLeft(), view.getTop(), view.getRight(), view.getBottom());
view.draw(c);
String filename = "graph.png";
File sd = Environment.getExternalStorageDirectory();
File dest = new File(sd, filename);
try {
FileOutputStream out = new FileOutputStream(dest);
b.compress(Bitmap.CompressFormat.PNG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
Log.i(TAG, filename);
}
The activity variable is an instance of AppCompatActivity. The R.layout.line_chart_layout's content:
<?xml version="1.0" encoding="utf-8"?>

Once the app is executed I get an image file called graph.png, but its content does not relfect the desire plot:
I have tried different values for view.setLayoutParams, view.layout, but it does not work... Some suggestions, please!

My guess is that graph.png looks so jumbled because the LineChart is never really added to the Activity's layout and so its "real size" is not calculated correctly. I know that you don't want to display the chart to the users but one can achieve that e.g. by setting the View invisible.
So here's my version:
public class MainActivity extends AppCompatActivity {
private LineChart lc;
private RelativeLayout view;
private static final String TAG = "LCTP Main";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

if(Build.VERSION.SDK_INT > 22 && (checkSelfPermission(WRITE_EXTERNAL_STORAGE) != PERMISSION_GRANTED)) {

}
else {
createLineChart(440.0);
}
}

for (int i = 0; i < length; i++) {
String permission = permissions[i];
if(grantResults[i] != PERMISSION_GRANTED){
Log.d(TAG, "onRequestPermissionsResult: missing permission " + permission);
ok = false;
}
}
if(ok){
createLineChart(220);
}
}
}
private void createLineChart(double frequency) {
if(lc == null){
view = findViewById(R.id.layParent);
lc = findViewById(R.id.lncMain);
}
lc.setData(createLineData(frequency));
view.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
view.getViewTreeObserver().removeOnGlobalLayoutListener(this);
Bitmap b = Bitmap.createBitmap(view.getMeasuredWidth(), view.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
view.layout(view.getLeft(), view.getTop(), view.getRight(), view.getBottom());
view.draw(c);
String filename = "graph.png";
File sd = Environment.getExternalStorageDirectory();
File dest = new File(sd, filename);
try {
FileOutputStream out = new FileOutputStream(dest);
b.compress(Bitmap.CompressFormat.PNG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
Log.i(TAG, filename);
}
});
lc.invalidate();
}
private LineData createLineData(double frequency) {
List<Entry> yVals = new ArrayList<>();
for(int i = 0; i < frequency; i = i + 10){
yVals.add(new Entry(i, (float)Math.sin(i*i)));
}
ILineDataSet lineDataSet = new LineDataSet(yVals, "LabelString");

return lineData;

Speeding up big set of programmatically created buttons display

I have an activity which generates a scrollable list (let's say a column) of programmatically created buttons from a List which is the result of an sqlite table read and my problem is that as the List is growing (and so the number of buttons) the initial painting of the screen is becoming slow (at the moment is taking 3 seconds with 50 buttons to draw) so I'm looking for a solution to this.
At first I thought of using a thread (runnable, handler or whatever is best), let's say creating a new thread inside the For which iterates over the list but it's not working (or at least I'm not being able to make it to work) so my question is the next:
Starting from a List<> which is the most appropiate way to create a big set of scrollable buttons so users doesn't have such delay when accesing the screen.
Paginating could be an option, but I'd like to know about other possibilities first and leave that as a last resource.
Thanks, and below is my code.
public static void createButtons(LinearLayout llContainer,
List<TestType> TestTypes, List<Test> Tests,
int buttonFontSize) {
Context oContext = llContainer.getContext();
String strTheme = TMAppearance.getThemeFromPreferences(oContext);
testMe = ((ApplicationConfiguration)oContext.getApplicationContext());
int callerActivity = TestTypes!=null ? 2 : 1;
if (TestTypes!=null || Tests!=null) {
int lCols = strTheme.equals(testMe.theme_vivid) ? 1 : 2;
//int sourceElementIndex = 0;
int originListSize = calculateOriginalListSize(callerActivity, TestTypes, Tests);
int lRows = (int) Math.ceil((double)originListSize/lCols);
List<String> aStartColors = TMUtils_ThemeVivid.generateStartColorArray(lRows, oContext);
List<String> aEndColors = TMUtils_ThemeVivid.generateEndColorArray(lRows, oContext);
for (i = 0; i < lRows; i++) {
LinearLayout outerButtonLayout = generateOuterButtonLayout(oContext);
for (j = 0; j < lCols; j++) {
final Thread r = new Thread() {
public void run() {
LinearLayout innerButtonLayout = generateInnerButtonLayout(oContext);
outerButtonLayout.addView(innerButtonLayout, j);
if (sourceElementIndex<originListSize){
final TMButton oButton = new TMButton(oContext);
if (callerActivity==1) { //testMenu
setTestMenuButtonSettings(oButton, sourceElementIndex, Tests);
} else {
if (callerActivity==2) { //testTypeMenu
setTestTypeMenuButtonSettings(oButton, sourceElementIndex, TestTypes);
}
}
if (strTheme.equals(testMe.theme_vivid)){
oButton.fontSize = buttonFontSize;
oButton.gradientStartColor = aStartColors.get(i);
oButton.gradientEndColor = aEndColors.get(i);

oButton.gradientStartColor = testMe.btnStartColor_purple;

0X0nosugar is correct. A RecycleView will provide better performance, but many beginners have more difficulty implementing it and with only 50 buttons performance shouldn't really be an issue. And although I generally like to abide by the rule 'Use the best available solution' I think it is still appropriate to learn how to implement the ListView. So...
You will need to create a custom adapter:
public class MyListDataAdapter extends ArrayAdapter<MyListData> {
private static final String TAG = "MyListDataAdapter";
public MyListDataAdapter(Context context, ArrayList<MyListData> data) {
super(context, 0, data);
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
final MyListData data = getItem(position);
if(convertView == null){
convertView = LayoutInflater.from(getContext()).inflate(R.layout.edit_list_item, parent, false);
}
// Add a TextView if you need one
final TextView tvName = (TextView) convertView.findViewById(R.id.tvName);
Button btnEditTicketHolder = (Button) convertView.findViewById(R.id.btnEdit);
btnEditTicketHolder.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
long userId = data.getUserId();
String fName = data.getFirstName();
Intent intent = new Intent(getContext(), EditActivity.class);
intent.putExtra("userId", userId);
intent.putExtra("fName", fName);
getContext().startActivity(intent);
}
});
String name = data.getFirstName();
tvName.setText(name);
return convertView;
}
}
Now you need your MyListData class to hold the data:
public class MyListData {
// Add more as you need
private long userId;
private String firstName;
public MyListData(){
}
public void setFirstName(String name){ this.firstName = name; }
public void setUserId(long id){ this.userId = id; }
public String getFirstName(){ return this.firstName; }
public long getUserId(){ return this.userId; }
}
Your custom ListView layout could look something like:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<LinearLayout
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
>
<TextView
android:id="#+id/tvName"
android:text="With Whom"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
>
<Button
android:id="#+id/btnEdit"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:paddingRight="10dp"
android:paddingLeft="10dp"
android:text="Edit"
android:backgroundTint="#color/colorAccent"
android:focusable="false"
/>
</LinearLayout>
</RelativeLayout>
In your Activity (eg. in the onCreate() method) where the ListView you will need to populate the data for the ListView. This should not be done on the UI Thread
ArrayList<MyListData> arrayListData = new ArrayList<MyListData>();
MyListDataAdapter adapter = new MyListDataAdapter(this, arrayListData);
for (MyListData g : result) {
adapter.add(g);
}
mLstMy.setAdapter(adapter);
Also in the activity where the ListView is to be maintained set up some onClick event handlers if you need them:
(I find that one of the small advantages of the ListView is that the onClick event is easier it implement than in the RecycleView)
mMyLst = (ListView) findViewById(lstMy);
mMyLst.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long l) {
MyListData data = (MyListData) parent.getItemAtPosition(position);
selectedName = data.getName();
Intent intent = new Intent(ShowListDataActivity.this, MainActivity.class);
startActivity(intent);
}
});
mMyLst.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> adapterView, View view, int i, long l) {
MyListData data = (MyistData) adapterView.getItemAtPosition(i);
selectedName = data.getFirstName();
selectedTicketPosition = i;
// removeValue is my own method for removing an entry from the
// list MyListData and then call adapter.notifyDataSetChanged();
removeValue(i);
return true;
}
});

How can i open a fragment tab from another fragment tab via button

You can use the replace() method on your fragment to replace the current fragment with another.
i.e.: replace(YourNewFragment.newInstance());
OR
If you don't want to actually replace the fragment, you can change tabs programmatically to the tab you want to display. If you are using a ViewPager this can be done by calling yourViewPager.setCurrentItem(indexToSet).
Let me know if this helps, or if you have any other questions in regard to my answer!

I was facing the same issue and i easily solved it by calling viewpager from the firstFragment class, and then easily setting the viewpager's current item to the index of the tab you want.
here's the code which i placed in the onClick method of the first tab fragment for me to go the third tab fragment;
ViewPager viewPager = getActivity().findViewById(R.id.simpleViewPager);
viewPager.setCurrentItem(2);
My answer might be late, but i hope it helps anyone else who might meet this challenge.

Android Custom BaseAdapter getView not called

So, I have scoured the interwebs and I cannot find a solution for this based on other people's experiences, so I am posting this issue. (Please note that this is my 1st android app experience and I am debugging / updating an existing app.)
When I implement my custom NotesListAdapter (extends BaseAdapter) on the ListView, mListNotesView (mListNotesView.setAdapter(this)), and load the data into the ArrayList mNoteList, the getView function is not being called. Also, I found that mListNotesView.setBackgroundResource is not chaning the background of the control, either. I have a similar implementation on a previous activity that works exactly correct. When I copied over the class and changed it to handle my ArrayList, it broke. I have getCount returning the ArrayList size(), which is not 0, and getItemId returns position. I have a feeling it may be my XML or my setup because it's acting like the ListView is not visible. I am perplexed. How do I get the ListView to show? Anything inside of the getView has not been reached so it may be buggy.

I'm going to recommend you reorganize your code. Here are some general tips:
1) Keep your views like ListView in the Activity class. Don't try to inflate the view in your adapter class. So in your activity's onCreate() after setContentView() you should have something like:
ListView listView = (ListView) findViewById(R.id.listView);
2) Next you need to get the data that will be shown in the listview and store it in a list. I didn't see in your code where the data comes from, but let's just say it comes from a database. You should create something like an ArrayList and store the data that you want to show in the ListView in the ArrayList
3) Next you need to create an adapter and pass the list of data into the adapter.
4) Once this has been done the ListView now has an adapter that will supply data to it. If you've done everything correctly then the system will eventually call getView() automatically and your code inside that should run and render the view.
Not an exact solution, but hopefully this explanation will help you figure it out.

Cardview Rounded Corners are not showing up in Screenshot? - java

I Noticed that you are trying to take a screenshot from 'mainRelative' which does not exist in your xml, I think you should use the id of 'cardView' or 'mainlinear' based on your requirements.
