//LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
LayoutInflater inflater = (LayoutInflater)getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);
View customView = inflater.inflate(R.layout.popup_layout,null);
mPopupWindow = new PopupWindow(
customView,
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT
);
Button btn_popup_submit = (Button)customView.findViewById(R.id.btn_popup_submit);
Button btn_popup_cancel = (Button)customView.findViewById(R.id.btn_popup_cancel);
btn_popup_submit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(getApplicationContext(), "aaa", Toast.LENGTH_SHORT).show();
Log.d("LOG","aaaa");
}
});
btn_popup_cancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(getApplicationContext(), "bbbb", Toast.LENGTH_SHORT).show();
Log.d("LOG","bbbb");
}
});
if(Build.VERSION.SDK_INT>=21){
mPopupWindow.setElevation(5.0f);//5.0f
}
mPopupWindow.showAtLocation(mRelativeLayout, Gravity.CENTER,0,0);
mPopupWindow.setFocusable(true);
mPopupWindow.setBackgroundDrawable(new ColorDrawable(ContextCompat.getColor(mContext, android.R.color.transparent)));
mPopupWindow.setOutsideTouchable(false);
mPopupWindow.setTouchable(false);
mPopupWindow.update();

to

How to show custom layout alert dialog at center vertical position

I want to display custom dialog at center vertical position but it appears at top.Above the first one is my xml file and second one is output after running in real device. Here is the code of dialog.
//alert dialog code
//add theme to display on whole page
AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this,
android.R.style.Theme_Holo_Light_NoActionBar_TranslucentDecor);
LayoutInflater inflater = this.getLayoutInflater();
//custom layout
View dialogView = inflater.inflate(R.layout.custom_bar, null);
dialogBuilder.setView(dialogView);
//button to close dialog box
Button closeButton = (Button)
dialogView.findViewById(R.id.closeButton);
final AlertDialog alertDialog = dialogBuilder.create();
closeButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
alertDialog.dismiss();
}
});
//show dialog
alertDialog.show();

In your main layout of custom_bar put android:gravity="center"

You should write like this.
AlertDialog dialog = new AlertDialog.Builder(this, R.style.Dark).create();
if (dialog.getWindow() != null)
{
Window window = dialog.getWindow();
window.setLayout(WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT);
window.setGravity(Gravity.CENTER);
dialog.getWindow().setBackgroundDrawableResource(android.R.color.background_dark);
}
This will show the alert dialog to the center of the screen.

Use this code to your Alert dialog to the center of the screen.
Add this in your class and change the code as per your needed.
//Internet Alert Dialog
public static void InternetAlert(final Context _A) {
final Dialog dialog = new Dialog(_A, R.style.CustomDialogStyle);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCanceledOnTouchOutside(true);
dialog.setContentView(R.layout.dialog_internet_connection);
final Button Yes = (Button) dialog.findViewById(R.id.btn_yes);
Yes.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();
}
If you want to fill the entire screen Just change the FrameLayout Height to match_parent
<?xml version="1.0" encoding="utf-8"?>

Add that line to your code. it will set the popup window to center.

Adjusting height of a Custom layout in a dialog

I have a dialog with custom layout, everything is working fine, except there is a big empty spaces at the bottom which i cannot remove.
Any suggestion how i can remove that empty space.
Here is my Code:
public Dialog onCreateDialog() {
final AlertDialog.Builder builder = new AlertDialog.Builder(
this);
// Get the layout inflater
LayoutInflater inflater = 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.dialogue_cover_staying, null))
// Add action buttons
.setPositiveButton("Done", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
//action
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
finish();
}
});
return builder.show();
}
My XML Layout:
`
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/back1"
android:orientation="vertical">
<TextView
android:id="#+id/textView2"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_weight="0.00"
android:background="#drawable/box"
android:gravity="center_vertical"
android:text="Enter Covers and Guest Type"
android:textAppearance="?android:attr/textAppearanceLarge" />
<EditText
android:id="#+id/et_covers"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="4dp"
android:layout_marginLeft="4dp"
android:layout_marginRight="4dp"
android:layout_marginTop="35dp"
android:fontFamily="sans-serif"
android:hint="Covers"
android:inputType="number" />
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginTop="30dp"
android:fontFamily="sans-serif"
android:text="Staying Guest...?"
android:textAppearance="?android:attr/textAppearanceMedium" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp" >
<CheckBox
android:id="#+id/checkYes"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="50dp"
android:text="YES" />
<CheckBox
android:id="#+id/checkNo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="75dp"
android:text="NO" />
</LinearLayout>
</LinearLayout> `

Change your layout width and height from "wrap_content" to "100dp" for example..like this..
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="100dp"
android:layout_height="200dp"
android:background="#drawable/back1"
android:orientation="vertical" >
Moreover you can set minWidth and minHeight..
android:minWidth="300dp"
android:minHeight="400dp"

Why is my alert dialog not showing all its contents

I am trying to customize my alert dialog with a layout. The problem is that the ALert dialog box is lunched with small size and most of the layout is trancated or words are overlapping. It is not screen issue as the dialog box is very small and does not seem to expand to cover all the contents. Why do you think this is happening?
I am using the following layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<LinearLayout
android:id="#+id/linearLayout2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/linearLayout1"
android:layout_alignParentLeft="true"
android:orientation="horizontal" >
<TextView
android:id="#+id/tvNa"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.5"/>
<EditText
android:id="#+id/etNa"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1" />
</LinearLayout>
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:orientation="horizontal" >
<TextView
android:id="#+id/tvQ"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.5"/>
<EditText
android:id="#+id/etQ"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1" />
</LinearLayout>
<LinearLayout
android:id="#+id/linearLayout3"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/linearLayout1"
android:layout_centerVertical="true"
android:orientation="horizontal" >
<TextView
android:id="#+id/tvP"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.5" />
<EditText
android:id="#+id/etP"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:inputType="numberDecimal" />
</LinearLayout>
</RelativeLayout>
And I am using the following code:
AlertDialog.Builder alert = new AlertDialog.Builder(this);
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.add_dialog, null);
alert.setView(layout);
alert.setTitle("New one");
alert.setPositiveButton("Ok",new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int whichButton) {
}
});
alert.setNegativeButton("Cancel",new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int whichButton) {
}
});
alert.show();

The Dialog Object has a set max size that you have not over written. You could add your layout to a ScrollView. Other than that you will have to follow the inheritances of the Dialog until you find where the max Dialog size is being set and override this. GrepCode is a good place to view the SDK source.
