How to simulate touch event with android at a given position?

AndroidMobile DevelopmentApps/Applications

This example demonstrates how do I simulate touch even with android at a given position.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:padding="4dp"
   tools:context=".MainActivity">
</RelativeLayout>

Step 3 − Add the following code to src/MainActivity.java

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.MotionEvent;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
   private boolean isTouch = false;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
   }
   @Override
   public boolean onTouchEvent(MotionEvent event) {
      int X = (int) event.getX();
      int Y = (int) event.getY();
      int eventAction = event.getAction();
      switch (eventAction) {
         case MotionEvent.ACTION_DOWN:
            Toast.makeText(this, "ACTION_DOWN "+"X: "+X+" Y: "+Y, Toast.LENGTH_SHORT).show();
            isTouch = true;
         break;
         case MotionEvent.ACTION_MOVE:
            Toast.makeText(this, "MOVE "+"X: "+X+" Y: "+Y,
               Toast.LENGTH_SHORT).show();
         break;
         case MotionEvent.ACTION_UP:
            Toast.makeText(this, "ACTION_UP "+"X: "+X+" Y: "+Y, Toast.LENGTH_SHORT).show();
         break;
      }
      return true;
   }
}

Step 4 − Add the following code to androidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest
   xmlns:android="http://schemas.android.com/apk/res/android"
   package="app.com.sample">
   <application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:supportsRtl="true"
      android:theme="@style/AppTheme">
      <activity android:name=".MainActivity">
         <intent-filter>
            <action
               android:name="android.intent.action.MAIN" />
            <category
               android:name="android.intent.category.LAUNCHER" />
         </intent-filter>
      </activity>
   </application>
</manifest>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run Play Iconicon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −
