Hello Ludwig,
Basically what I meant was that, I have a class Screen1.java and it
has a button in it clicking to which should switch to another screen
which also has one nore button.Clicking on the other button in the
second screen should end the activity(child activity).This was the
simplest code that I wanted to implement to work with changing
screens, but when I run this application in the ddms logcat I can find
only creash report and a pop up saying the application has stopped
unexpectedly in the emulator.
Please let me know if I am doing some thing wrong.
I am pasting below the code snippet for Screen1.java:
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.screen1);
Button b = (Button) findViewById(R.id.btnClick);
b.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
Intent i = new Intent(Screen1.this, Screen2.class);
startActivity(i);
}
});
}
(In the screen1.xml there is a button component along with a TestView
to display a text)
Code snippet for Screen2.java;
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.screen2);
Button b = (Button) findViewById(R.id.btnClick2);
b.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
setResult(RESULT_OK);
finish();
}
});
}
(In the screen2.xml there is a button component along with a TestView
to display a text)
And the androidmanifest.xml;
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android";
package="ScreenChangeProj.pac"
android:versionCode="1"
android:versionName="1.0.0">
<application android:icon="@drawable/icon" android:label="@string/
app_name">
<activity android:name=".Screen1"
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=".Screen2" android:label="Screen 2">
</activity>
</application>
</manifest>
Regards,
Susama
