Why my android application has stopped?

My project won't open on my device, it say's "Unfortunately,myApp has stopped".
this is my manifest:
this is my activity java :
package bismillah.project;
import android.app.Activity;

I tried your code and I had to delete some stuff from your XML file because it was creating some bugs. It might be related to me but here's your XML I was able to use:
But please do not change your XML file before trying the solution below. If it still doesn't work, you should consider the elements I removed.

Next I created your Project2Activity java class and activity2 (pretty much empty since you gave no info about it).
So when trying to run your application you get the following error:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.application.so/com.example.application.so.Project2Activity}: java.lang.NumberFormatException: For input string: ""
and it is at :
at com.example.application.so.Project2Activity.onCreate(Project2Activity.java:24)
now if we consider this lines 23 and 24:
String value=pek.getText().toString(); // line 23
final int pekerja=Integer.parseInt(value); // line 24
The error is that you are trying to read (line 23) your editText Value at the creation of the activity, at that time, your editText is still blank which means value will be equal to "" (empty string).
What you want to do instead is to put your lines from 22 to 33 (the ones below) in a button click event, I tried putting them in your button 1 click event and your app doesn't crash any more:
EditText pek=(EditText)findViewById(R.id.editText1);
String value=pek.getText().toString();
final int pekerja=Integer.parseInt(value);
EditText lam=(EditText)findViewById(R.id.editText2);
String value1=lam.getText().toString();
final int lama=Integer.parseInt(value1);
EditText up=(EditText)findViewById(R.id.editText3);
String value2=up.getText().toString();
final int upah=Integer.parseInt(value2);
EditText jum=(EditText)findViewById(R.id.editText4);
String value3=jum.getText().toString();
final int jumlah=Integer.parseInt(value3);
So to summarize, the problem is that you are extracting empty strings from your editTexts and trying to make integers out of them. Instead try making that all reading and integer extracting process on the click of a button where your really need these inputs. just like get the inputs and the final moment.
You should pay attention to your logcat (error messages), it is quite helpful.
What you can also do is to verify that your editTexts are not empty while trying to extract strings from them and raise exception or Toast if they are empty. Nothing too complicated just something like:
if (value.equals("")):
// editText is empty so do something
You can refer to this link for further understanding of how to know when an editText is empty.

TextView text animation is restarted if the text is changed in another TextView

In TextView1 text animation runs from right to left, and in TextView2 constantly changing text. The problem is that when I perform TextView2.setText ( "...") in the text animation TextView1 restarted. Is it possible to prevent the restart of the animation?
XML code TextView1:
<TextView

Thanks in advance.

Try to wrap your TextView1 with LinearLayout.

Check Activity class TextView object and its assign id.

getText() returns empty string (android studio)

I have a little question here about android development.
I already searched on internet, but i still can't find the solution.
I want to getText() from a view, but it just returns an empty ("") string.
Here's my .java code:
public void kotakCentang(View view)
{
RelativeLayout vwParentRow = (RelativeLayout)view.getParent();
TextView id_test = (TextView)vwParentRow.getChildAt(0);
TextView nama_test = (TextView)vwParentRow.getChildAt(1);
tugas_status = (TextView)vwParentRow.getChildAt(5);
tanggalKasih = (EditText)vwParentRow.getChildAt(6);
tanggalKumpul = (EditText)vwParentRow.getChildAt(8);
waktuKasih = (EditText)vwParentRow.getChildAt(7);
waktuKumpul = (EditText)vwParentRow.getChildAt(9);
tugasKompleksitas = (EditText)vwParentRow.getChildAt(10);
Tugas tugas = new Tugas();
TugasRepo tugass = new TugasRepo(this);
tugas.nama = nama_test.getText().toString();
tugas.waktuDikasih = waktuKasih.getText().toString();
tugas.waktuDikumpul = waktuKumpul.getText().toString();
tugas.tanggalDikasih = tanggalKasih.getText().toString();
tugas.tanggalDikumpul = tanggalKumpul.getText().toString();
tugas.kompleksitas=Integer.parseInt(tugasKompleksitas.getText().toString());
tugasKompleksitas.getText().toString();
}
The getText() which returns empty string is just the tugas.waktuDikasih, and tugas.waktuDikumpul .
Thank you for your help.

How to set list view height programatically in android

I am making an application in which my keyboard comes up on the activity and it hides may header view (layout) I have searched and tried adjust pane state hidden,adjust nothing all the attributes in manifest but nothing solved my problem then I found one the posts over stackover flow that you can calculate the spacing then set the height I implemented but the behaviour is still same this is the sanpshot when activity comes
but when keyborad pops up it hides my header view this is snapshot of what's happening
this is my manifest code
<activity
android:name="com.dd.sproutchat.ChatActivity"
android:label="#string/app_name"
android:screenOrientation="portrait"
android:windowSoftInputMode="adjustNothing">
</activity>
this is my layout of that activity

and this is my activity code for calculating height of listview
private static boolean keyboardHidden = true;
private static int reduceHeight =0;
final View decorView = this.getWindow().getDecorView();
decorView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
Rect rect = new Rect();
decorView.getWindowVisibleDisplayFrame(rect);
int displayHeight = rect.bottom - rect.top;
int height = decorView.getHeight();
boolean keyboardHiddenTemp = (double) displayHeight / height > 0.8;
int mylistviewHeight = Lv_Chat.getMeasuredHeight();
if (keyboardHiddenTemp != keyboardHidden) {
keyboardHidden = keyboardHiddenTemp;
if (!keyboardHidden) {
reduceHeight = height - displayHeight;
RelativeLayout.LayoutParams mParam = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, mylistviewHeight - reduceHeight);
Lv_Chat.setLayoutParams(mParam);
Lv_Chat.requestLayout();
} else {
RelativeLayout.LayoutParams mParam = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, mylistviewHeight + reduceHeight);
Lv_Chat.setLayoutParams(mParam);
Lv_Chat.requestLayout();
}
}
}
});
I have also tried this link for setting xml file
http://codetheory.in/android-add-views-view-groups-listview-gridview/
any help please

To change the height of ListView you should use LayoutParams:
ViewGroup.LayoutParams param = listView.getLayoutParams();
param.height = anynumberhere;
listView.setLayoutParams(param);
listView.requestLayout();
According to your question, this is the way to change the ListView's height, but i don't think its the rite approach to make that header of yours stay in its place.

I think you should use adjustResize instead of adjustNothing and add android:fitsSystemWindows="true" in your root RelativeLayout instead of programmatically trying to resize your views.

list activity onListItemClick does not firing

I nedd to click on items in list activity to do something, but its not working
i search for this problem and saw some answers about this such as :
android:focusable="false"
android:clickable="false"
android:focusableInTouchMode="false"
or
android:descendantFocusability="afterDescendants"
android:descendantFocusability="beforeDescendants"
android:descendantFocusability="blocksDescendants"
but those are not worked
this is my listActivity :
public class TrainListActivity extends SherlockListActivity
{
public static String varStart = "com.example.traininfo.startcity";
public static String varDestination = "com.example.traininfo.destinationcity";
private String start;
private String destination;
ArrayList<TrainType> trains;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_trainlist);
Log.i("SearchTrain", "try to get extras...");
start = getIntent().getExtras().getString(varStart);
destination = getIntent().getExtras().getString(varDestination);
TrainController tc = new TrainController(this);
trains = new ArrayList<TrainType>();
trains = tc.getTrainList(start, destination).getTrain();
Log.i("SearchTrain", "got the train list...");
TrainListAdapter adapter = new TrainListAdapter(this, trains);
Log.i("SearchTrain", "adapter initialized successfully!!");
setListAdapter(adapter);
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id)
{
// I want to do something here :(
super.onListItemClick(l, v, position, id);
Log.i("trainList", "on click");
}
}

please help me :(

Use normal activity and put a ListView in xml. Use inflator to use your custom row design. Just put the focusable=false for your imagebutton. It will allow you to click on the row and you can apply a separate click listener for your imagebutton to handle its click separately.

I faced the same problem not too long ago. It seems that the ImageButton takes focus regardless what you do. What I did was to replace the ImageButton with and ImageView and set the listener to it.
This is how your xml files should look like.
