我正在通过一个Android应用程序开发手册并且在几个教程中遇到一些问题，因为它们都崩溃了“这种启动被配置为在挂起时打开Debug透视图”。
我在查询LogCat或Debug透视图时并不是很聪明，但我认为应用程序失败了，因为启动时间超时了。我怀疑这是关于我的import语句（可能是import android.app.ListFragment语句），但如果是这样，我不确定该怎么办。
顺便说一下，我已经尝试了我自己编写的代码和发布商网站上的源代码，但它们都崩溃了。
这是Fragment1活动的代码：
import android.app.ListFragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;
public class Fragment1 extends ListFragment {
String[] presidents = {
"Dwight D. Eisenhower",
"John F. Kennedy",
"Lyndon B. Johnson",
"Richard Nixon",
"Gerald Ford",
"Jimmy Carter",
"Ronald Reagan",
"George H. W. Bush",
"Bill Clinton",
"George W. Bush",
"Barack Obama"
};
@Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment1, container, false);
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_1, presidents));
}
public void onListItemClick(ListView parent, View v,
int position, long id)
{
Toast.makeText(getActivity(),
"You have selected " + presidents[position],
Toast.LENGTH_SHORT).show();
}
}
我的布局文件的代码：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<fragment
android:id="@+id/fragment1"
android:name="net.rogw.ListFragment.Fragment1"
android:layout_width="0dp"
android:layout_height="200dp"
android:layout_weight="0.5" />
<fragment
android:id="@+id/fragment2"
android:name="net.rogw.ListFragment.Fragment1"
android:layout_width="0dp"
android:layout_height="300dp"
android:layout_weight="0.5" />
</LinearLayout>
很抱歉LogCat现在添加了延迟...
