hi all,
this is my situation: i have a library project, and a project
referencing it. I know that is very simple to redefine any resource in
my project, because in cases where a resource ID is defined in both
the application and the library, the tools ensure that the resource
declared in the application gets priority and that the resource in the
library project is not compiled into the application .apk ( from
android developers web site ).
But: how can i do to redefine source (for example, override an
activity) in my project?
I have implemented some code samples, to better explain my problem:
In my library project, i have two activities:
*AndroidLibraryExampleActivity:
********************************************************************
package com.nolanofra.app.androidLibraryExample;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
public class AndroidLibraryExampleActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void onSecondActivityGo (View v)
{
Intent intent = new Intent(AndroidLibraryExampleActivity.this,
SecondLibraryActivity.class);
startActivity(intent);
}
**********************************************************************************************
and SecondLibraryActivity:
**************************************************************
package com.nolanofra.app.androidLibraryExample;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class SecondLibraryActivity extends Activity{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second_activity);
TextView t = (TextView) findViewById(R.id.textView);
t.setText("Hello, i'm second activity on library!!!");
}
}
**********************************************************************************************
Manifest of library project is:
************************************************************
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android";
package="com.nolanofra.app.androidLibraryExample"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />
<application android:icon="@drawable/icon" android:label="@string/
app_name">
<activity android:name=".AndroidLibraryExampleActivity"
android:label="@string/app_name">
</activity>
<activity android:name=".SecondLibraryActivity"
android:label="@string/app_name">
</activity>
</application>
</manifest>
*************************************************************************************************
In my project referencing library, I want to redefine
SecondLibraryActivity in order to change text displayed in text view,
for example I would like to do some of this:
package com.nolanofra.app.sampleProjectUsingLibrary;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
import com.nolanofra.app.androidLibraryExample.R;
public class SecondLibraryActivity extends Activity{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second_activity);
TextView t = (TextView) findViewById(R.id.textView);
t.setText("Hello, i'm second activity on project!!!");
}
}
***************************************************************************************
Android Manifest on project is:
**************************************************
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android";
package="com.nolanofra.app.sampleProjectUsingLibrary"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />
<application android:icon="@drawable/icon" android:label="@string/
app_name">
<activity
android:name="com.nolanofra.app.androidLibraryExample.AndroidLibraryExampleActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category
android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.nolanofra.app.androidLibraryExample.SecondLibraryActivity">
</activity>
</application>
</manifest>
**************************************************************************************************************
So, how can I do that ? Is it possible to overwrite, in my project,
the activity declared in the library in order to change its behavior?
Thanks
