這裏是我所遵循的YouTube教程項目中的所有代碼。 (主部分) ProjectActivity:應用程序凍結按鈕點擊
package justinehume.Project;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class ProjectActivity extends Activity{
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button tut1 = (Button) findViewById(R.id.tutorial1);
tut1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
startActivity(new Intent("android.intent.action.TUTORIALONE"));
}
});
}
protected void onPause(){
super.onPause();
}
}
main.xml中
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:orientation="vertical">
<Button android:id="@+id/tutorial1" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="Button" />
</LinearLayout>
ProjectManifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="justinehume.Project"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<application
android:icon="@drawable/ic_launcher"

</intent-filter>
</activity>
</application>
</manifest>
Tutorialone.java
package justinehume.Project;
import android.app.Activity;
import android.os.Bundle;
public class Tutorialone extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.tutorial1);
}
}
ë當應用程序在SDK中運行時,我很快點擊該按鈕,應用程序崩潰並且強制關閉。有任何想法嗎? 謝謝!

請發佈LogCat輸出。 – Abhijit 2012-04-11 15:07:13
嘗試使用'new Intent(ProjectActivity.this,Tutorialon.class)'開始您的活動,而不是現在正在使用的內容。此外,發佈你的logcat堆棧跟蹤的力量關閉。 – 2012-04-11 15:07:46
