To get the Width and the height of the Android Screen we can use the below code,
package com.code2care.tools.sample;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Display;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView tv = (TextView) findViewById(R.id.textView);
Display disp = getWindowManager().getDefaultDisplay();
//Displays the Width and Height of the screen
tv.setText("Width : " + disp.getWidth() +"\n" +" Height : "+disp.getHeight());
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
