I have a class that extends LinearLayout. It contains simply two EditBox. On some button click, i want to load this class inside the alert Dialog. When i click on button, the alert dialog is displayed but the view class that extends LinearLayout is not displayed.The code is as follows. I am stucked into this. Can I get some solution??
public class StudentDialog extends LinearLayout {
Context context;
LinearLayout layout;
public StudentDialog(Context context) {
super(context);
this.context = context;
createStudentDialog();
}
private void createStudentDialog() {
layout = new LinearLayout(context);
layout.setOrientation(LinearLayout.VERTICAL);
layout.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT));
layout.setPadding(10, 10, 10, 10);
layout.setId(200);
EditText studentName = new EditText(context);
studentName.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
studentName
.setTextAppearance(getContext(), TEXT_DIRECTION_FIRST_STRONG);
EditText address = new EditText(context);
address.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
address.setTextAppearance(getContext(), TEXT_DIRECTION_FIRST_STRONG);
layout.addView(studentName);
layout.addView(address);
}
}
//Now i am calling this on some button click listener as follows. The alert dialog is displayed but not the StudentDialog.
StudentDialog dialog = new StudentDialog(this);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
alertDialogBuilder.setView(dialog);
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();
It should work if you change
alertDialogBuilder.setView(dialog);
as
alertDialogBuilder.setView(dialog.layout);
Do you want to show two edit text in a alert view just like a login dialog with button, if yes then just create a layout which you want to show in dialog view. Create a class which extends Dialog and set this layout in setContentView of onCreate of this class

I am writing an android app,
I have an activity, inside it i have a button, and it's on click listener opens a dialog box from a custom XML using the following code:
I would like to add that dialog box another button that is not set in it's XML file.
All the components are excising in the XML and working just fine, the dialog opens but I can't add the b button.
this.addCheer.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final Dialog d = new Dialog(map.this);
LinearLayout layout = findViewById(R.id.dialog_layout_root);
LayoutInflater layoutInflater = d.getLayoutInflater();
d.requestWindowFeature(Window.FEATURE_NO_TITLE);
d.setContentView(R.layout.cheer_dialog);// custom layout for the dialog
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.copyFrom(d.getWindow().getAttributes());
lp.width = WindowManager.LayoutParams.MATCH_PARENT;
lp.height = WindowManager.LayoutParams.MATCH_PARENT;
d.show();
d.getWindow().setAttributes(lp);
final EditText title = d.findViewById(R.id.cheerDialogText);
ImageButton addCheerOk = (ImageButton) d.findViewById(R.id.addCheerOk);
Button b = new Button(d.getContext());
b.setText("yo");
cheerDialogLayout.addView(b, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));
}
I tried to use this example but it does not work for me. What am i doing wrong here?
Thanks!
Just try below code
this.addCheer.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final Dialog d = new Dialog(map.this);
LayoutInflater layoutInflater = d.getLayoutInflater();
d.requestWindowFeature(Window.FEATURE_NO_TITLE);
d.setContentView(R.layout.cheer_dialog);// custom layout for the dialog
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.copyFrom(d.getWindow().getAttributes());
lp.width = WindowManager.LayoutParams.MATCH_PARENT;
lp.height = WindowManager.LayoutParams.MATCH_PARENT;
d.show();
d.getWindow().setAttributes(lp);
LinearLayout layout = d.findViewById(R.id.dialog_layout_root);
final EditText title = d.findViewById(R.id.cheerDialogText);
ImageButton addCheerOk = (ImageButton) d.findViewById(R.id.addCheerOk);
Button b = new Button(d.getContext());
b.setText("yo");
layout.addView(b, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));
}
You were using only findViewById(R.id.dialog_layout_root); instead of d.findViewById(R.id.dialog_layout_root);
Here ll_button is the id of layout which contains the two xml buttons you have.
LinearLayout ll_button = d.findViewById(R.id.ll_button);
LinearLayout.LayoutParams layoutParams = new inearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
ll_button.addView(b, layoutParams);
Remove your last line.
cheerDialogLayout.addView(b, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));
i have dialog with onclick button and include final Dialog dialog = new Dialog(context); how i can add cancel button to my dialog for hide dialog
and my content layout is different from activity main layout
sorry for my language
my code :
public void showd(View view){
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.custom);
dialog.setCanceledOnTouchOutside(false);
dialog.show();
}
You should use a DialogBuilder instead of creating the Dialog yourself. You then can create a cancel button using the following code
// Create your dialog builder
AlertDialog.Builder builder = new AlertDialog.Builder(context);
// Apply your custom view
builder.setView(R.layout.custom);
// A null clickListener will cancel the dialog
builder.setNegativeButton("Cancel" /*TODO Replace with string resources*/, null);
// Show the dialog
builder.show();
I am trying to build a alert box in android studio, i have 2 xml and 1 activity class where on click of a button i want to show the other layout.
I am getting a error, here is my code of MainActivity
cancelBookingButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
LayoutInflater inflater = getLayoutInflater();
View alertLayout = inflater.inflate(R.layout.alert_cancel_confirm, null);
final TextView disAgree = (TextView) alertLayout.findViewById(R.id.TextDisagree);
final TextView Agree = (TextView) alertLayout.findViewById(R.id.TextAgree);
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Current Booking");
// This will set the view from XML inside ALertDialog
alert.setView(alertLayout);
// disabling cancel of AlertDialog on click of back button and outside touch
alert.setCancelable(false);
AlertDialog dialog = alert.create();
dialog.show();
}
});
In this line i am getting error
AlertDialog.Builder alert = new AlertDialog.Builder(this);
In Builder cannot be applied
Any idea why i am getting this.
AlertDialog.Builder alert = new AlertDialog.Builder(YourActivity.this);
alert.setTitle("Current Booking");
// This will set the view from XML inside ALertDialog
alert.setView(alertLayout);
// disabling cancel of AlertDialog on click of back button and outside touch
alert.setCancelable(false);
AlertDialog dialog = alert.create();
dialog.show();
If I want add 2 buttons to JFrame in Java with each press on certain button I create JPanel and add this 2 buttons to the Jpanel then add the JPanel to the JFrame
But in android I tried
public class object extends Activity {
ToggleButton togglebutton;
Button button;
public void onCreate(Bundle bundle){
super.onCreate(bundle);
LinearLayout layout = new LinearLayout(this);
layout.setOrientation(LinearLayout.HORIZONTAL);
layout.setWeightSum(100);
LinearLayout.LayoutParams par = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT,30);
LinearLayout.LayoutParams part = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT,70);
togglebutton = new ToggleButton(this);
button = new Button(this);
button.setLayoutParams(par);
button.setLayoutParams(part);
layout.addView(button);
layout.addView(togglebutton);
LinearLayout lay =(LinearLayout)findViewById(R.id.lay);
try {
lay.addView(layout);
}catch(Exception e){
e.printStackTrace();
}
}
}
But didn't work I always get exception with that
What can I do?
Or what is equal to JPanel in Android?
You said nothing about "adding content from one Activity to other" in your initial post and didn't include an a logcat for your exception, but the obvious problem is not calling setContentView while using findViewById.
This code creates the activity you are trying to make.
public class MainActivity extends Activity {
ToggleButton togglebutton;
Button button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LinearLayout rootView = new LinearLayout(this);
rootView.setOrientation(LinearLayout.HORIZONTAL);
rootView.setWeightSum(100);
LinearLayout.LayoutParams par = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT,30);
LinearLayout.LayoutParams part = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT,70);
togglebutton = new ToggleButton(this);
button = new Button(this);
button.setText("Click Me");
button.setLayoutParams(par);
button.setLayoutParams(part);
rootView.addView(button);
rootView.addView(togglebutton);
setContentView(rootView);
}
}
The closest thing to JPanel for android would be the root view of your layout. I think cricket has the right solution and your getting an error beacuse your not setting setContentView(). This will set your root view to the xml layout file specified. For example setContentView(R.layout.main);.
How do I add a popup dialog over the call screen? I'll be using the BroadcastReceiver to listen for incoming calls and show it. I need an idea about how to write an activity that allows a dialog over an incoming call. Also, how do I make the dialog movable to any part of the screen? I already have the BroadcastRceiver implemented and performing other functions, so I could just use an intent and start the activity from this BroadcastRceiver
start an activity, then use AlertDialog Builder from that activity to prompt a dialog
set custom view to customize the dialog appearence
Try this
AlertDialog.Builder builder = new AlertDialog.Builder(context.getApplicationContext());
LayoutInflater inflater = LayoutInflater.from(context);
View dialogView = inflater.inflate(R.layout.caller_dialog, null);
ImageView button = dialogView.findViewById(R.id.close_btn);
builder.setView(dialogView);
final AlertDialog alert = builder.create();
alert.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
alert.getWindow().setType(WindowManager.LayoutParams.TYPE_PHONE);
alert.setCanceledOnTouchOutside(true);
alert.show();
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
Window window = alert.getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
window.setGravity(Gravity.TOP);
lp.copyFrom(window.getAttributes());
//This makes the dialog take up the full width
lp.width = WindowManager.LayoutParams.MATCH_PARENT;
lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
window.setAttributes(lp);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//close the service and remove the from from the window
alert.dismiss();
}
});
