In my Android application I created a custom DialogFragment with a custom View but I want the Positive and Negative Button with transparent background.
So I saw some SO answers and i did something like this:
private class PersonalInfoDialogFragment extends DialogFragment {
#Override
public void onStart(){
super.onStart();
Button pButton = ((AlertDialog) getDialog()).getButton(DialogInterface.BUTTON_POSITIVE);
Button nButton = ((AlertDialog) getDialog()).getButton(DialogInterface.BUTTON_NEGATIVE);
pButton.setBackgroundColor(getResources().getColor(Color.TRANSPARENT));
nButton.setBackgroundColor(getResources().getColor(Color.TRANSPARENT));
}
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
LayoutInflater inflater = getActivity().getLayoutInflater();
final View view=inflater.inflate(R.layout.personalinformation_dialog, null);
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle(R.string.personalinformation)
.setView(view)
.setPositiveButton(R.string.edit, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//Some code
}
})
.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// User cancelled the dialog
}
});
// Create the AlertDialog object and return it
final AlertDialog dialog = builder.create();
//I also tried this: dialog.getButton(DialogInterface.BUTTON_POSITIVE).setBackgroundColor(Color.TRANSPARENT);
return dialog;
}
}
I don't get why I am facing NullPointerException. Any idea?
public Button pButton ,nButton ;
#Override
public void onStart(){
super.onStart();
}
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
LayoutInflater inflater = getActivity().getLayoutInflater();
final View view=inflater.inflate(R.layout.personalinformation_dialog, null);
pButton = ((AlertDialog) getDialog()).getButton(DialogInterface.BUTTON_POSITIVE);
nButton = ((AlertDialog) getDialog()).getButton(DialogInterface.BUTTON_NEGATIVE);
pButton.setBackgroundColor(getResources().getColor(Color.TRANSPARENT));
nButton.setBackgroundColor(getResources().getColor(Color.TRANSPARENT));
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle(R.string.personalinformation)
.setView(view)
.setPositiveButton(R.string.edit, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//Some code
}
})
.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// User cancelled the dialog
}
});
// Create the AlertDialog object and return it
final AlertDialog dialog = builder.create();
//I also tried this: dialog.getButton(DialogInterface.BUTTON_POSITIVE).setBackgroundColor(Color.TRANSPARENT);
return dialog;
}
}

I am using a slightly different approach in order to keep the dialog open when a button is pressed:
AlertDialog.Builder builder = new AlertDialog.Builder(NewTableActivity.this);
builder.setTitle(R.string.addComponent);
final EditText titleText = new EditText(NewTableActivity.this);
titleText.setHint(R.string.title);
builder.setView(titleText);
builder.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener(){
#Override
public void onClick(DialogInterface dialogInterface, int i){
dialogInterface.cancel();
}
});
builder.setPositiveButton(R.string.ok, null);
final AlertDialog alertDialog = builder.create();
alertDialog.setOnShowListener(new DialogInterface.OnShowListener(){
#Override
public void onShow(DialogInterface dialogInterface){
Log.i("TEst", "Doung");
Button button = alertDialog.getButton(AlertDialog.BUTTON_POSITIVE);
}
}
The dialog is opened a little lower (this works too), but the Log is never called
AlertDialog.Builder builder = new AlertDialog.Builder(NewTableActivity.this);
builder.setTitle(R.string.addComponent);
final EditText titleText = new EditText(NewTableActivity.this);
titleText.setHint(R.string.title);
builder.setView(titleText);
builder.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.cancel();
}
});
builder.setPositiveButton(R.string.ok, null);
final AlertDialog alertDialog = builder.create();
alertDialog.setOnShowListener(new DialogInterface.OnShowListener() {
#Override
public void onShow(DialogInterface dialogInterface) {
Log.e("TEst", "Doung");
Button button = alertDialog.getButton(AlertDialog.BUTTON_POSITIVE);
}
});
alertDialog.show();
I build an AlertDialog box with
public class ConstantDialogFragment extends DialogFragment {
private AlertDialog.Builder builder;
private AlertDialog alertDialog;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final int[] constantProtocol = {0};
builder = new AlertDialog.Builder(getActivity(), AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);
builder.setTitle(getResources().getString(R.string.some_message))
.setMultiChoiceItems(R.array.some_choice, null,
new DialogInterface.OnMultiChoiceClickListener() {
#Override
public void onClick(DialogInterface dialog, int which,
boolean isChecked) {
// some method
}
})
.setPositiveButton(getResources().getString(R.string.ok_dialog), new DialogInterface.OnClickListener() {
class LoadConfigTask {
private ProgressDialog dialog;
private Activity activity;
public LoadConfigTask(Activity activity) {
this.activity = activity;
dialog = new ProgressDialog(activity, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);
}
public void execute() {
try {
// some method
} catch (Exception e) {
// some method
}
}
}
#Override
public void onClick(DialogInterface dialog, int id) {
// some method
}
})
.setNegativeButton(getResources().getString(R.string.cancel_dialog), new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
// some thing
}
});
builder.create();
alertDialog = builder.show();
return alertDialog;
}
public AlertDialog getAlertDialog(){
return alertDialog;
}
Then I tried this espresso implementation:
onView(withText("my first choice")).
perform(click());
and I get
NoMatchingViewException: No views in hierarchy found matching: with text: is my string"
How can I fix that ?
Fetching in the Android source code, I found useful methods. So to get control on the items of the AlertDialog, I had to do that
ListView listView = alertDialog.getListView();
View child = listView.getChildAt(0);
child.performClick();
I'm making a simple to do list and I want to be able to click on the item and enter a new text which will then replace the text of the TextView in that cell. I've got the dialogAlert working, I just don't know how to grab the cell's TextView and change it
This is what the Activity looks like,
public class MainActivity extends AppCompatActivity {
private ListDataSource ds;
private ListView listViewToDo;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Context context = this;
Log.d("MainActivity","Attempting to create data source");
try {
ds = new ListDataSource();
}
catch(Exception e)
{
e.printStackTrace();
Log.d("MainActivity","Failed to create data source");
}
Log.d("Main Activity","Attempting to link empty list view to on screen view");
listViewToDo = (ListView)findViewById(R.id.listOfLists);
Log.d("Main Activity","Views linked, Attempting to set adapter to listView");
listViewToDo.setAdapter(new ListDataSourceAdapter(this, ds));
Log.d("Main Activity", "Successfully set Adapter");
// add button listener
listViewToDo.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> parent, View view, final int position, long id)
{
AlertDialog.Builder editItem = new AlertDialog.Builder(context);
final EditText edittext = new EditText(context);
editItem.setTitle("Change Item");
editItem
.setMessage("Set new todo item")
.setView(edittext)
.setCancelable(false)
.setPositiveButton("Submit", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int id)
{
//what do I put here?
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int id)
{
dialog.cancel();
}
});
AlertDialog alertDialog = editItem.create();
alertDialog.show();
}
});
}
}
ds.remove(position);
ds.add(position,edittext.getText().toString().trim())
ListDataSourceAdapter adapter = new ListDataSourceAdapter(this, ds)
listViewToDo.setAdapter(adapter );
adapter.notifDataSetChanged();
When I write this code, it only shows dialog with one button, but not showing check boxes.
I don't know what's the problem.
private void showDialog(){
final ArrayList selectedItems = new ArrayList();
AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);
dialogBuilder.setTitle("asdasd");
dialogBuilder.setMessage("asdasd");
final String[] options = {"asd", "dsa","asd","aa"};
dialogBuilder.setMultiChoiceItems(options, null, new DialogInterface.OnMultiChoiceClickListener() {
#Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
if(isChecked){
selectedItems.add(which);
}else if(selectedItems.contains(which)){
selectedItems.remove(Integer.valueOf(which));
}
}
});
dialogBuilder.setNegativeButton("CANCEL",null);
AlertDialog dialog = dialogBuilder.create();
dialog.show();
};
Just see this link, and here is some code:
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle(R.string.pick_color);
.setItems(R.array.colors_array, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// The 'which' argument contains the index position
// of the selected item
}
});
return builder.create();
}
Hope you can solve your problem.
Whenever I debug the application it crashes when I click the button that pops up the dialog.
What should I do to make that dialog work?
public class Actionbar_BtnHandler extends Activity {
Context context;
public Actionbar_BtnHandler (Context context)
{
this.context=context;
}
public void btn_handler (Button btn_mic,Button btn_post)
{
btn_mic.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(context,"MICROPHONE",Toast.LENGTH_LONG).show();
}
});
btn_post.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
AlertDialog.Builder builder = new AlertDialog.Builder(context);
// Get the layout inflater
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
// Inflate and set the layout for the dialog
// Pass null as the parent view because its going in the dialog layout
builder.setView(inflater.inflate(R.layout.dialog_signin, null))
// Add action buttons
.setPositiveButton("Post", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
// sign in the user ...
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
builder.create();
}
});
}
}
Thanks in advance...
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
is inaccurate... The cast seems to fail
Try :
#Override
public void onClick(View v) {
AlertDialog.Builder builder = new AlertDialog.Builder(context);
// Get the layout inflater
LayoutInflater inflater = Actionbar_BtnHandler.this.getLayoutInflater();
Try this write your AlertDialog code using Handler..
btn_post.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Handler handler = new Handler();
handler.post(MessagealertDisplay);
}
});
}
Runnable MessagealertDisplay = new Runnable() {
#Override
public void run() {
AlertDialog.Builder builder = new AlertDialog.Builder(context);
// Get the layout inflater
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
// Inflate and set the layout for the dialog
// Pass null as the parent view because its going in the dialog layout
builder.setView(inflater.inflate(R.layout.dialog_signin, null))
// Add action buttons
.setPositiveButton("Post", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
// sign in the user ...
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
builder.create();
}
};
i used
Actionbar_BtnHandler btns = new Actionbar_BtnHandle(Class.this);
btns.btn_handler(btn_post, btn_mic);
instead of
Actionbar_BtnHandler btns = new Actionbar_BtnHandler(getApplicationContext);
btns.btn_handler(btn_post, btn_mic);
and it worked
