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
package com.exercise.AndroidScreen;
import android.app.Activity;
import android.os.Bundle;
import android.util.DisplayMetrics;
import android.widget.TextView;
public class AndroidScreenActivity extends Activity {
/** Called when the activity is first created. */
@Override
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);
}
}
