Get an Display Resolution of the Screen

android.util.DisplayMetrics is a structure describing general information about a display, such as its size, density, and font scaling.

To use android.util.DisplayMetrics to get resolution:

Create a dummy Android Application, add a TextView in main.xml to display the result.

<TextView
android:id="@+id/strScreenSize"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text=""
/>

Modify the .java file to read DisplayMetrics

 public void onCreate(Bundle savedInstanceState) {

         super.onCreate(savedInstanceState);

         setContentView(R.layout.main);

     

            DisplayMetrics dm = new DisplayMetrics();

            getWindowManager().getDefaultDisplay().getMetrics(dm);

            String str_ScreenSize = "The Android Screen is: "

                        + dm.widthPixels

                        + " x "

                        + dm.heightPixels;

            TextView mScreenSize = (TextView) findViewById(R.id.strScreenSize);

            mScreenSize.setText(str_ScreenSize);

     }
