How To Make Android Progress Bar Action in Android Studio

Step-01: First Make Progress Bar On Android MainActivity.XML Like Following..

<LinearLayout android:layout_width="match_parent" android:layout_height="match_parent"> <ProgressBar style="@android:style/Widget.ProgressBar.Horizontal" android:progressBackgroundTint="#ffffff" android:layout_marginTop="300dp" android:progressTint="#ff22" android:id="@+id/progressBarId" android:layout_width="match_parent" android:layout_height="20dp" /> </LinearLayout>

Step-02: Now Write Some Java Code At MainActivity.Java

public class MainActivity extends AppCompatActivity { int progress; private ProgressBar progressBar; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); progressBar= (ProgressBar) findViewById(R.id.progressBarId); Thread thread=new Thread(new Runnable() { @Override public void run() { doWork(); } }); thread.start(); } public void doWork() { for(progress=20;progress<=100; progress=progress+20 ) { try { Thread.sleep(1000); progressBar.setProgress(progress); } catch (InterruptedException e) { } } } }
