Sequential display of images automatically
<p>I am using the code below to display images sequentially via button click. Now I want to display these images automatically after a particular time period. They should be displayed and change after a particular time and where the addition will be needed in the same code.</p>

<pre><code>import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Button;
import android.widget.ImageView;


public class MainActivity extends AppCompatActivity {

private static ImageView imgView;
private static Button ButtonSbm;
private int current_image_index;
int [] images={R.mipmap.ic_launcher,R.mipmap.ic_launcher1};
@Override

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    FloatingActionButton fab=(FloatingActionButton)findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
Snackbar.make(view, "Replace with your own action",Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show();
        }
    });
    buttonClick();
}
public void buttonClick(){
imgView =(ImageView)findViewById(R.id.imageView);
ButtonSbm=(Button)findViewById(R.id.button);
ButtonSbm.setOnClickListener(
        new View.OnClickListener(){
        public void onClick(View v){
            current_image_index++;
            current_image_index=current_image_index %images.length;
                    imgView.setImageResource(images[current_image_index]);
        }
        }

    );

  }
@Override
   public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
 }

@Override
 public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
 }
 }
