In the below code I have created Runnable Thread program in android. Here first I have added TextView in activity_main.xml layout. In MainActivity I have used handler class then I have created a new Runnable interface , And I have also used onStart (),run() and update() method. You can see below example code it clearly describe you How to make Runnable Thread in android.
Step(1)activity_main.xml layout-
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text=" Runnable Thread"
android:textAlignment="center"
android:textSize="20dp"/>
<TextView
android:id="@+id/one"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
Step(2)- MainActivity-
public class MainActivity extends AppCompatActivity {
int i = 0;
TextView raj;
Handler handler = new Handler(){
@Override
public void handleMessage(Message msg) {
// TODO Auto-generated method stub
update_i();
}
};
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
raj =(TextView)findViewById(R.id.one);
}
@Override
protected void onStart() {
// TODO Auto-generated method stub
super.onStart();
Thread myThread=new Thread(new Runnable() {
public void run() {
while(true){
try {
handler.sendMessage(handler.obtainMessage());
Thread.sleep(1000);
}
catch (Throwable t) {
}
}
}
});
myThread.start();
}
private void update_i()
{
i++;
raj.setText(String.valueOf(i));
}
}
