我很困惑使用ListFragment ......我無法理解問題出在哪裏？的Android ListFragment是混亂的
這裏是我FragmentActivity類：
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
public class menu extends FragmentActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.root_menu);
if (getSupportFragmentManager().findFragmentById(android.R.id.content) == null) {
ListFrag list = new ListFrag();
getSupportFragmentManager().beginTransaction().replace(android.R.id.content, list).commit();
}}}
我ListFragment類：
public class ListFrag extends ListFragment {
int Files = 0;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
getListView().setBackgroundResource(R.drawable.table);
getListView().setDividerHeight(0);
getListView().setCacheColorHint(0);
View view = inflater.inflate(R.layout.main, null);
return view;
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
setListAdapter(new CustomListAdapter(getActivity(), getThemes()));
}
public String[] getThemes(){
...
return ...;
}
而且main.xml中（它是用於製作清單，自定義列表適配器我做了）：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="40dp"
android:paddingTop="30dp"
android:cacheColorHint="#00000000"
android:layout_marginTop="100px"
>
<ImageView
android:id="@+id/icon"
android:layout_height="40dp"
android:layout_width="40dp"
android:src="@drawable/check" >
</ImageView>
<TextView
android:id="@+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@+id/label"
android:paddingTop="6dp"
android:paddingLeft="20dp"
android:textSize="25px" >
</TextView>
</LinearLayout>
這root_menu.xml應顯示在頂部的背景圖像和列表的片段：
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/back"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/back"
android:cacheColorHint="#00000000"
>
<fragment
android:id="@+id/frag"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.osmgames.kartuves.ListFrag" >
</fragment>
</LinearLayout>
這是我CustomListAdapter類：
public class CustomListAdapter extends ArrayAdapter<String> {
private final Context context;
private final String[] values;
public CustomListAdapter(Context context, String[] values) {
super(context, R.layout.main, values);
this.context = context;
this.values = values;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.main, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.label);
ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);
textView.setText(values[position]);
imageView.setImageResource(R.drawable.check);
return rowView;
}
}

我看到它說contentview沒有創建，但我不明白爲什麼...
實際上有什麼問題？ – Shaiful
