Question

I’m creating an app. but now i want it to open a other app with a imagebutton. i searched google for like 5 days there are many awnsers but not the right one.

there are awnsers but not the full explaination.

i found this part

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(new ComponentName("com.package.address","com.package.address.MainActivity"));
startActivity(intent);


but where do i have to put this so it works on my imagebutton. and what classes or things do i have to make.

This is my appactifity.java

    package eu.cornholio.rom;

import android.app.Activity;
import android.os.Bundle;

public class CornholioROMActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }


}

and this is my main.xml

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:settings="http://schemas.android.com/apk/res/com.android.settings"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/imageView1"
        android:gravity="center"
         android:layout_gravity="center"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/cornh" android:contentDescription="@string/cornholio"/>

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="@string/cornholio" />

    <ImageButton
        android:id="@+id/imageButton1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/cwm" android:clickable="true" android:contentDescription="@string/cmw"/>

    <ImageButton
        android:id="@+id/imageButton2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/jkay"
         android:clickable="true"
          android:contentDescription="@string/jkay"/>


</LinearLayout>            

here my code

    package eu.cornholio.rom;

import android.app.Activity;
import android.content.ComponentName;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageButton;

public class CornholioROMActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        //finding your image button
        ImageButton btn = (ImageButton) findViewByid(R.id.imageButton1);

        //setting onClick listener
        btn.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(Intent.ACTION_MAIN);
                intent.setComponent(new ComponentName("eu.chainfire.cfroot.cwmmanager",
                                       "eu.chainfire.cfroot.cwmmanager.MainActivity"));
                startActivity(intent); 
            }
        });

    }

}

Answer 1

set onClickListener to your ImageButton.

yourImageButton.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.setComponent(new ComponentName("com.package.address",
                               "com.package.address.MainActivity"));
        startActivity(intent); 
    }
});

Update

for example, if you want to set click action on imageButton1, then you need to do the following changes in your onCreate method:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    //finding your image button
    ImageButton btn = (ImageButton) findViewById(R.id.imageButton1);

    //setting onClick listener
    btn.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(Intent.ACTION_MAIN);
            intent.setComponent(new ComponentName("com.package.address",
                                   "com.package.address.MainActivity"));
            startActivity(intent); 
        }
    });

}
