Unable to set the width of custom dialog in Android

Question

I am developing an Android app. In my app, I am trying to show an alert dialog setting custom view. Setting custom view is ok. But I am having problem with setting the width of my dialog. I cannot set the width. It is always default with.

This is how I show dialog

AlertDialog.Builder builder = new AlertDialog.Builder(context);
            View view = layoutInflater.inflate(R.layout.meme_post_actions_dialog,null);
            builder.setView(view);
            builder.create().show();

This is xml layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:gravity="center"
    android:orientation="vertical" android:layout_width="100dp"
    android:layout_height="match_parent">
    <TextView
        android:text="This is dialog"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</LinearLayout>

As you can see I set the width to 100dp. So it width will be too small. But this is what I got.

How can I set the width of the custom alert dialog?

There might be the number of ways you can control it. Let me share with you one of the approaches by setting alert window width and height.

AlertDialog.Builder builder = new AlertDialog.Builder(this);
View view = layoutInflater.inflate(R.layout.meme_post_actions_dialog,null);
        builder.setView(view);
builder.setView(layout);
alertDialog = builder.create();
alertDialog.show();
alertDialog.getWindow().setLayout(600, 400); //<--Controlling width and height.

In last make sure that parent of your layout should match parent.

android:layout_width="match_parent"
android:layout_height="match_parent"

How can I get it? – Wai Yan Hein Oct 15 '16 at 06:10
its not a good solution. what if mobile screen is very small...we should not give fixed height and width..as @Ahmad Aghazadeh answer we should calculate the screen first. Acc to screen we can make dialog. – Däñish Shärmà Oct 15 '16 at 06:11
LayoutParams.WRAP_CONTENT – Bhavdip Sagar Oct 15 '16 at 06:14
@DäñishShärmà As I already mentioned that there are multiple ways. – Bhavdip Sagar Oct 15 '16 at 06:15

Try this :

AlertDialog.Builder builder = new AlertDialog.Builder(context);
            View view = layoutInflater.inflate(R.layout.meme_post_actions_dialog,null);
            builder.setView(view);
int width = (int)(getResources().getDisplayMetrics().widthPixels*0.50); //<-- int width=400;
int height = (int)(getResources().getDisplayMetrics().heightPixels*0.50);//<-- int height =300;
AlertDialog alertDialog = builder.create();
alertDialog.getWindow().setLayout(width, height);
