android eclipse button OnClick event

android, android-layout, eclipse, java, xml

Solution

For managing click activity in android ,you can do as below

Implement `OnClickListener` on YourActivity.java class like

`public class MainActivity extends Activity implements OnClickListener`

Then, declare your button in .java class like

`Button btn = (Button) findViewById(R.id.btnPlay);`

Then use button `btn` variable as below

btn.setOnClickListener(new View.OnClickListener() {

    public void onClick(View v) {
        myClick(v); /* my method to call new intent or activity */
    }
});

Handle the click event:

public void myClick(View v) {
    Intent intent = new Intent(**this, Swipe.class**);
    startActivity(intent);// for calling the activity
}

you also need to register your activity(.java) in `android manifest` as below

<activity
    android:name=".Swipe"
    android:screenOrientation="landscape" >
</activity>

Problem

I have 2 files: main_activity.xml and home.xml. I made a button in main_activity.xml Here is the code snippet: ``` <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:background="@drawable/splash_background" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" > <Button android:id="@+id/Home" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:layout_marginRight="43dp" android:onClick="home" android:text="Home" /> </RelativeLayout> ``` And then, I have my home.xml. I want the button to open up home.xml. How can i do this? I don't know any java and I am new to android development. Here is my home.xml below: ``` <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:background="@drawable/app_bg" android:layout_height="match_parent" android:orientation="vertical" > </LinearLayout> ``` And below is my AndroidManifest.xml: ``` <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.idozer" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17" /> <application android:allowBackup="false" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name="com.example.idozer.SplashActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="com.example.idozer.MainActivity" android:label="@string/app_name" > </activity> </application> </manifest> ``` And that's all I have. Please, if you reply, tell me where to add the code such as the directory or between code snippets.
