What is a dialog window in Android?

A dialog is a small window that prompts the user to make a decision or enter additional information. A dialog does not fill the screen and is normally used for modal events that require users to take an action before they can proceed. Dialog Design.

How do I make my dialog bigger on Android?

According to Android platform developer Dianne Hackborn in this discussion group post, Dialogs set their Window's top level layout width and height to WRAP_CONTENT . To make the Dialog bigger, you can set those parameters to MATCH_PARENT .


I used this code to show the dialog at the bottom of the screen:

Dialog dlg = <code to create custom dialog>;

Window window = dlg.getWindow();
WindowManager.LayoutParams wlp = window.getAttributes();

wlp.gravity = Gravity.BOTTOM;
wlp.flags &= ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;
window.setAttributes(wlp);

This code also prevents android from dimming the background of the dialog, if you need it. You should be able to change the gravity parameter to move the dialog about


private void showPictureialog() {
    final Dialog dialog = new Dialog(this,
            android.R.style.Theme_Translucent_NoTitleBar);

    // Setting dialogview
    Window window = dialog.getWindow();
    window.setGravity(Gravity.CENTER);

    window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
    dialog.setTitle(null);
    dialog.setContentView(R.layout.selectpic_dialog);
    dialog.setCancelable(true);

    dialog.show();
}

you can customize you dialog based on gravity and layout parameters change gravity and layout parameter on the basis of your requirenment


I found this code snippet from @gypsicoder code here

private CharSequence[] items = {"Set as Ringtone", "Set as Alarm"};
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setItems(items, new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int item) {

        if(item == 0) {

        } else if(item == 1) {

        } else if(item == 2) {

        }
    }
});

AlertDialog dialog = builder.create();
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
WindowManager.LayoutParams wmlp = dialog.getWindow().getAttributes();

wmlp.gravity = Gravity.TOP | Gravity.LEFT;
wmlp.x = 100;   //x position
wmlp.y = 100;   //y position

dialog.show();

Here x position's value is pixels from left to right. For y position value is from bottom to top.


New BottomSheetDialog:

BottomSheetDialog dialog = new BottomSheetDialog(YourActivity.this);    
dialog.setContentView(YourView);

dialog.show();

For me, this worked out pretty well where I was trying to position my dialog somewhere exactly at the bottom of the textview where it gets selected.

public void setPosition(int yValue) {
    Window window = getWindow();
    WindowManager.LayoutParams param = window.getAttributes();
    param.gravity = Gravity.TOP | Gravity.CENTER_HORIZONTAL;
    param.y = yValue;
    window.setAttributes(param);
    window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
}

just add this to your code:

dialog.getWindow().setGravity(Gravity.BOTTOM);
