I’ve an Activity with two tabs. In the first one there’s a Button. If this Button is pressed, a new TableRow is created in the second tab. This works fine.
Each TableRow has 3 views(an image, some text and a button). Each time a Button is created i assign an id to it (0,1,2…).
What I want is to set a certain text if the id is 0,1,2…whichever of that ids.
I’ve tried this but it’s not working:
public void onClick(View arg0) {
// TODO Auto-generated method stub
switch(arg0.getId()){
case R.id.save:
if (et.getText() !=null && thumbnail != null){
TableRow tr = new TableRow(this);
ImageView view = new ImageView(this);
TextView view2 = new TextView(this);
Button view3 = new Button(this);
view3.setOnClickListener(this);
titulo = new String[500];
mensaje = new String[500];
fotos = new Bitmap[500];
view.setImageBitmap(thumbnail);
view.setPadding(1, 5, 0, 0);
view.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
Calendar c = Calendar.getInstance();
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd");
titulo[i]=""+et.getText();
mensaje[i]=""+et1.getText();
fotos[i]=thumbnail;
i++;
view2.setText("" + et.getText() + dateFormat.format(c.getTime()) );
view2.setGravity(Gravity.CENTER_HORIZONTAL);
view2.setGravity(Gravity.CENTER_VERTICAL);
view3.setGravity(Gravity.RIGHT);
view3.setGravity(Gravity.CENTER_VERTICAL);
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
tr.addView(view, metrics.widthPixels/3, 150);
tr.addView(view2, metrics.widthPixels/2, 100);
tr.addView(view3, metrics.widthPixels/6, 20);
tl.addView (tr, 0);
final Toast toastMensaje = Toast.makeText(getApplicationContext(),
"Tu entrada se cargó correctamente", Toast.LENGTH_LONG);
toastMensaje.setGravity(Gravity.CENTER, 0, 0);
toastMensaje.show();
et.setText("");
et1.setText("");
i1.setVisibility(View.GONE);
}
else{
final Toast toastMensaje = Toast.makeText(getApplicationContext(),
"Tienes que añadir un título y una foto", Toast.LENGTH_LONG);
toastMensaje.setGravity(Gravity.CENTER, 0, 0);
toastMensaje.show();
}
break;
case R.id.photo:
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
break;
case R.id.gallery:
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, TFRequestCodes);
break;
}
for (int j=0; j<titulo.length; j++){
if (arg0.getId()==j){
final Toast toastMensaje = Toast.makeText(getApplicationContext(),titulo[j], Toast.LENGTH_LONG);
toastMensaje.setGravity(Gravity.CENTER, 0, 0);
toastMensaje.show();
}
}
}
What is not working is this piece of code:
for (int j=0; j<titulo.length; j++){
if (arg0.getId()==j){
final Toast toastMensaje = Toast.makeText(getApplicationContext(),titulo[j], Toast.LENGTH_LONG);
toastMensaje.setGravity(Gravity.CENTER, 0, 0);
toastMensaje.show();
}
}
And this is the XML file:

You should not initialize those in the onClick()
By doing so, everytime you click save , new objects are created and you wont be able to store your strings. Move them to onCreate().
Is i a global variable too?
