Send different requestCode for different imageView click, And onActivityResult check the request code set image data to your imageView
capturedImageButton.setOnClickListener( new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent photoCaptureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(photoCaptureIntent, 100);
}
});
capturedImageButton1.setOnClickListener( new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent photoCaptureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(photoCaptureIntent, 101);
}
});
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(resultCode == RESULT_OK){
switch (this.resultCode){
case 100:
Bitmap bitmap = (Bitmap)data.getExtras().get("data");
capturedImageButton.setImageBitmap(bitmap);
break;
case 101:
Bitmap bitmap = (Bitmap)data.getExtras().get("data");
capturedImageButton1.setImageBitmap(bitmap);
break;

I have an ImageView for which I wanted to implement the onClickListener. But when I click on the image, nothing happens. Event the Logcat does not show any errors.
Something is happening with the clickability attribute.
My XML code:
<ImageView
android:id="#+id/img2"
android:layout_width="104dp"
android:layout_height="126dp"
android:layout_weight="1"
android:padding="8dp"
android:scaleType="centerCrop"
android:clickable="true"
android:src="#drawable/ic_person_black_24dp"
tools:ignore="MissingConstraints"
tools:layout_editor_absoluteX="-3dp"
tools:layout_editor_absoluteY="14dp"
android:focusable="true" />
Code in Fragment:
public class DialogFrag extends DialogFragment {
private ImageView img2;
private static final int IMAGE_PICK_CODE = 1000;
private final int CODE_MULTIPLE_IMG_GALLERY = 2;
#RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
#NonNull
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.dialog_layout, container, false);
img2 = (ImageView) view.findViewById(R.id.img2);
img2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent, IMAGE_PICK_CODE);
}
});
return view;
}
#Override
public void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
int CODE_IMG_GALLERY = 1;
if (requestCode == CODE_IMG_GALLERY && resultCode == RESULT_OK) {
Uri imageUri = data.getData();
if(imageUri!=null){
img2.setImageURI(imageUri);
}
}
if (requestCode == CODE_IMG_GALLERY && resultCode == RESULT_OK) {
Uri imageUri = data.getData();
if(imageUri!=null){
img2.setImageURI(imageUri);
}
}
}
#RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder=new AlertDialog.Builder(getActivity());
return builder
.setTitle("Заполните анкету")
.setView(R.layout.dialog_layout)
.setPositiveButton("OK", null)
.setNegativeButton("Отмена", null)
.create();
}
}
Where is my mistake?
Help please)
Please override the onViewCreated() and use the view object
kotlin code:
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
img2 = view.findViewById(R.id.img2);
// Implement onclicklistener
}
This should be of any help I guess.
I have create simple image view and set a frame and set button is x and y coordinates before set x and y coordinates this time button click event work but set x and y coordinates not working button click event.

can you please replace onClick(View view) method with following.
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.btnCapture:
final Dialog dialog = new Dialog(MainActivity.this);
dialog.setContentView(R.layout.custom_dialog_box);
dialog.setTitle("Select Image");
Button dialogButton = (Button) dialog.findViewById(R.id.btnExit);
dialogButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
Button btnChoosePath = (Button) dialog.findViewById(R.id.btnChoosePath);
btnChoosePath.setOnClickListener(new View.OnClickListener() {
#RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN)
#Override
public void onClick(View v) {
activeGallery();
dialog.dismiss();
}
});
Button btnTakePhoto = (Button) dialog.findViewById(R.id.btnTakePhoto);
btnTakePhoto.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
activeTakePhoto();
dialog.dismiss();
}
});
dialog.show();
break;
}
}
Edited Answer.
Change the following thing in you MainActivity.class
btnCapture.setX(300);
btnCapture.setY(850);
and replace your xml file with the following.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:id="#+id/FrameLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/viewImage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="matrix" />
</FrameLayout>
<ImageView
android:id="#+id/abc"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/blue_squre" />
</RelativeLayout>
<ImageButton
android:id="#+id/btnCapture"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher" />
And One thing in your xml you use btnCapture id for Button. and you create the object of ImageButton in your .class file. how its works for you i don't know. but i change it try it.

Getting NullPointerException here:
captureImage.setImageBitmap(thumbnail);
I don't know why I am getting captureImage null. As I have define it globally. Why it is null as I have defined it inside the dialog box.
Well your captureImage belongs to the view of your first alert dialog (the one created in openDialogToAddReminder method.
I suspect that upon clicking on the captureImage to select the image, this dialog gets dismissed so it destroys the captureImage reference, hence when the onActivityResult is called there is no more captureImage object.
You can check the above if you set a dismiss listener on your AlertDialog.Builder e.g.
alertDialogBuilder.setOnDismissListener(new OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog) {
Log.d("onDismiss");
}
});
place this code right above:
AlertDialog alertDialog = alertDialogBuilder.create();
EDIT:
If you receive on your logcat: "onDismiss" this means that my assumption is correct. Try to resolve it by:
alertDialog.setCanceledOnTouchOutside(false);
Currently I create an app which has the camera function that allows users to select their image or do capturing.I get the tutorial from https://stackoverflow.com/a/22165449/5261462. But I want the selected image intent to another page instead of just displaying on imageView. The image need to fix the screen and can add caption at below like whatsapp.
This is what I've tried so far.
Everything start from Project1.java, with the imagebutton.
public void addListenerOnButton() {
imageButton = (ImageButton) findViewById(R.id.imageButton);
imageButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
ImageFitScreen i = new ImageFitScreen();
i.selectImage();
}
});
}
ImageFitScreen.java
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.image_fit_screen);
b = (ImageView) findViewById(R.id.imageView3);
t = (EditText) findViewById(R.id.editText38);
u = (EditText) findViewById(R.id.editText39);
}
public void selectImage() {
final CharSequence[] options = { "Take Photo", "Choose from Gallery","Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(ImageFitScreen.this);
builder.setTitle("Add Photo!");
builder.setItems(options, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
if (options[item].equals("Take Photo"))
{
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(intent, 1);
}
else if (options[item].equals("Choose from Gallery"))
{
Intent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 2);
}
else if (options[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
}

But I get error as below when the imageButton in Project1.java is clicked.

(Project1.java:80)
i.selectImage();
I am seriously in dire need of some advice. Can someone please please assist me with some advice. PLEASE : )?
From what I understood, ImageFitScreen is an activity and should be started using an Intent i.e.
Intent i = new Intent(Project1.this,ImageFitScreen.class);
startActivity(i);
If you look at the exception, it tells you that context is null ie. ImageFitScreen.this is null at the line
AlertDialog.Builder builder = new AlertDialog.Builder(ImageFitScreen.this);
This is because, activity will only have a context if it is started by the activitymanager. We use intent to ask activitymanger to start an activity. Hope it helps you.
UPDATE:
You can use ImageFitScreen to hold imageview and edittext for caption. Then start ImageFitScreeen when you need the user to pick an image. And onCreate of ImageFitScreen you can start selectImage() function ie.
Project1.java
public void addListenerOnButton() {
imageButton = (ImageButton) findViewById(R.id.imageButton);
imageButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Intent i = new Intent(Project1.this,ImageFitScreen.class);
startActivity(i);
}
});
}
ImageFitScreen.java
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.image_fit_screen);
b = (ImageView) findViewById(R.id.imageView3);
t = (EditText) findViewById(R.id.editText38);
u = (EditText) findViewById(R.id.editText39);
selectImage();
}
public void selectImage() {
final CharSequence[] options = { "Take Photo", "Choose from Gallery","Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(ImageFitScreen.this);
builder.setTitle("Add Photo!");
builder.setItems(options, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
if (options[item].equals("Take Photo"))
{
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(intent, 1);
}
else if (options[item].equals("Choose from Gallery"))
{
Intent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 2);
}
else if (options[item].equals("Cancel")) {
dialog.dismiss();
finish();
}
}
});
builder.setOnKeyListener(new Dialog.OnKeyListener() {
#Override
public boolean onKey(DialogInterface dialog, int keyCode,
KeyEvent event) {
// TODO Auto-generated method stub
if (keyCode == KeyEvent.KEYCODE_BACK) {
finish();
dialog.dismiss();
}
return true;
}
});
builder.show();
}
In my app I have a ListView for listing some textviews and buttons ,also have an ImageView on the top,i have added parallax scrollview between this,now I want to add some textviews and buttons dynamically in the ListView . I have this code ;but it is not working.I am a beginner,so I could not find the actual problem. Can anybody help me out,and Please excuse my language problem?
