Question

我正在尝试使用listview创建一个dialogfragment，并使用此问题中接受的答案来执行此操作

How to display an existing ListFragment in a DialogFragment

但是当我尝试打开片段对话框并且应用崩溃时，我收到了Error inflating class fragment

以下是dialog_fragment_with_list_fragment布局

<?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="match_parent"
android:orientation="vertical" >

 <fragment
         android:id="@+id/flContent"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:padding = "10dp"
         class="com.OptimusApps.stayhealthy.AndroidXMLParsingActivity" />

</LinearLayout>

并且它不是导致它失败的androidxmlparsingactivity片段，我已经尝试了其他片段并且它们也无法正常工作

下面是我的对话框片段类

public class BodyDialogue extends DialogFragment {
int mNum;

/**
 * Create a new instance of MyDialogFragment, providing "num"
 * as an argument.
 */
static BodyDialogue newInstance(int num) {
    BodyDialogue f = new BodyDialogue();

    // Supply num input as an argument.
    Bundle args = new Bundle();
    args.putInt("num", num);
    f.setArguments(args);

    return f;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mNum = getArguments().getInt("num");

    // Pick a style based on the num.
    int style = DialogFragment.STYLE_NORMAL, theme = 0;
    switch ((mNum-1)%6) {
        case 1: style = DialogFragment.STYLE_NO_TITLE; break;
        case 2: style = DialogFragment.STYLE_NO_FRAME; break;
        case 3: style = DialogFragment.STYLE_NO_INPUT; break;
        case 4: style = DialogFragment.STYLE_NORMAL; break;
        case 5: style = DialogFragment.STYLE_NORMAL; break;
        case 6: style = DialogFragment.STYLE_NO_TITLE; break;
        case 7: style = DialogFragment.STYLE_NO_FRAME; break;
        case 8: style = DialogFragment.STYLE_NORMAL; break;
    }
    switch ((mNum-1)%6) {
        case 4: theme = android.R.style.Theme_Holo; break;
        case 5: theme = android.R.style.Theme_Holo_Light_Dialog; break;
        case 6: theme = android.R.style.Theme_Holo_Light; break;
        case 7: theme = android.R.style.Theme_Holo_Light_Panel; break;
        case 8: theme = android.R.style.Theme_Holo_Light; break;
    }
    setStyle(style, theme);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.dialog_fragment_with_list_fragment, null);

    return view;

}
}

这就是我如何调用dialogfragment

public void onClick(View v) {
                BodyDialogue  dialogFragment = BodyDialogue.newInstance(1);
                 dialogFragment .setRetainInstance(true);
                 dialogFragment .show(getFragmentManager(), "bodydialogue");
            }

这是logcat中的原因

但是当我尝试打开时，我收到一个错误的类错误片段对话框和应用程序崩溃

这种情况正在发生，因为您将BodyDialogue片段的视图用作已包含其他片段（通过fragment标记）的布局。这将失败，因为不允许嵌套片段从xml布局中膨胀，因为the guide for the nested fragments已经提到：

注意：当布局包含＆lt;时，您不能将布局扩展为片段。片断＆gt ;.只有在动态添加到片段时才支持嵌套片段。

因此，如果您想在AndroidXMLParsingActivity对话框片段中嵌入BodyDialogue（片段命名错误btw），请使用{{1在同一onCreateView回调中的代码中执行此操作}}

我使用这个简单易用的

我的代码使用上面的回答

@Override
public void onClick(View v) {

// TODO Auto-generated method
                                        // stub

FragmentTransaction ft2 = getFragmentManager().beginTransaction();
                                        ft2.remove(getFragmentManager().findFragmentByTag("one"));
                                        ft2.commit();

dialog.dismiss();

}

我的xml

<fragment
            android:id="@+id/map"
            android:name="com.google.android.gms.maps.MapFragment"
            android:layout_width="match_parent"
            android:layout_height="220dip"
            android:tag="one"
            android:layout_below="@+id/txtTargetStreet_hint"
            android:layout_margin="20dip" />
