And here is my output.I want to increase the width and height of the dialog.
And my java file
public class MyDialogFragment extends DialogFragment {
public MyDialogFragment() {
}
private EditText mEditText;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.dialogfragment, container);
// mEditText = (EditText) view.findViewById(R.id.txt_your_name);
// getDialog().setTitle("Hello");
getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE);
return view;
}
}
Change your dialog dimension on runtime:
yourDialog.show();
yourDialog.getWindow().setLayout((6 * width)/7, LayoutParams.WRAP_CONTENT);
You can do that for both dimension, in my example i only changed the width. Hope it helps!
EDIT
I forgot to mention where i took width:
DisplayMetrics metrics = getResources().getDisplayMetrics();
int width = metrics.widthPixels;
int height = metrics.heightPixels;
EDIT 2
Try this code:
Dialog yourDialog = dialogFragment.getDialog();
yourDialog.getWindow().setLayout((6 * width)/7, (4 * height)/5);
Setting android:minWidth and android:minHeight in the custom layout does the trick for me.
put below line in onCreate
setStyle(DialogFragment.STYLE_NO_TITLE, android.R.style.Theme_Holo_Light_Dialog_NoActionBar_MinWidth);
Narendra
<style name="full_screen_dialog" parent="@android:style/Theme.Dialog">
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
<item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:minWidth" type="dimen">600dp</item>
</style>
Use this in style.xml file and use this style in dialog class
The right solution is to override the onCreateDialog method rather than onCreateView, and create your dialog with a AlertDialog.Builder, as explained in the doc: http://developer.android.com/reference/android/app/DialogFragment.html#AlertDialog
Dialogs are sized by their content. You can add padding and margins on the outer layout to consume more space, but that will not redistribute the views inside.
Try this
For setting dialog width and height as per device screen size
Display display;
int DisplayWidth, DisplayHeight, DialogWidth, DialogHeight;
Dialog dialog;
display =((WindowManager)activity_context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
DisplayWidth = display.getWidth();
DisplayHeight = display.getHeight();
if(DisplayHeight > DisplayWidth)
{
DialogWidth = (6 * DisplayWidth) / 7 ;
DialogHeight = (4 * DisplayHeight) / 5 ;
}
else
{
DialogWidth = (6 * DisplayWidth) / 9 ;
DialogHeight = (4 * DisplayHeight) / 5 ;
}
dialog = new Dialog(activity_context);
// Set your dialog width and height dynamically as per your screen.
Window window = dialog.getWindow();
window.setLayout(DialogWidth,DialogHeight);
window.setGravity(Gravity.CENTER);
dialog.show();
try to set android:layout_height to some value for base LinearLayout
for example
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
<!-- right here -->
android:layout_height="100dp"
android:background="@color/white"
android:orientation="vertical" >
Add android:minWidth / android:minHeight to your root view. See example below:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:minWidth="300dp"
android:minHeight="500dp">
