How to get Device Density in Android | Get Device Resolution in Android | Get Device Height and Width of Android Device Programmatic

Hello Friends, I am sharing code for get density size, height, width of Android device. Just copy paste below code and enjoy..

Print Screen:

1)MainActivity.java

package com.example.densityproject;

import android.app.Activity;
import android.os.Bundle;
import android.util.DisplayMetrics;
import android.util.Log;
import android.view.Display;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends Activity {
 TextView textView;
 Button button;
 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  button = (Button) findViewById(R.id.button1);
  textView = (TextView) findViewById(R.id.textView1);
  button.setOnClickListener(new OnClickListener() {

   @Override
   public void onClick(View v) {
    DisplayMetrics metrics = new DisplayMetrics();
    Display mDisplay = MainActivity.this.getWindowManager()
      .getDefaultDisplay();
    getWindowManager().getDefaultDisplay().getMetrics(metrics);
    float screenDensity = metrics.density;
    float screenDensityDPI = metrics.densityDpi;
    int width = mDisplay.getWidth();
    int Height = mDisplay.getHeight();

    Log.e("Density:", String.valueOf(screenDensity + "---"
      + screenDensityDPI));

    textView.setText("Device Density=" + screenDensity + "Height="
      + Height + "Width=" + width);

   }
  });

 }

}

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
