我正在尝试做一些应该简单的事情,我的主要布局是这样的

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/mainContainer"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <fragment
        android:name="io.raindance.kalimat.grid.GridFragment"
        android:id="@+id/gridControlInMainView" 
        android:layout_width="match_parent"
        android:layout_height="match_parent" />        

</LinearLayout>

主要活动中没有 Java 代码;现在 GridFragment 的代码和布局是这样的:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/gridFragmentMainContainer"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    >

</LinearLayout>

Java 代码:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    // Load the layout of the rack tile
    View view = inflater.inflate(R.layout.grid_fragment, null, false);



    // Get the root linear layout to add the rows to it
        LinearLayout root = (LinearLayout) view.findViewById(R.id.gridFragmentMainContainer);

        // Build the rows of the grid
            int rowsId = 21;
        for (int i = 0; i < 15; i++) {
            // Create the linear layout that represents a row in the grid
            LinearLayout row = new LinearLayout(this.getActivity());
            row.setId(rowsId++);
            row.setOrientation(LinearLayout.HORIZONTAL);

            row.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 10, 1.0f));

            // Build the cells of the grid
            for (int j = 0; j < 15; j++) {
                // Create the cell fragment
                CellFragment cellFragment = new CellFragment();
            // Add the cell fragment to the row fragment
                            this.getFragmentManager().beginTransaction().add(row.getId(), cellFragment).commit();
}
        // Add the row to the root element
        root.addView(row);
    }

    return view;
}

CellFragment 布局如下所述,没有 Java 代码。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/lll1"
    android:layout_weight="1"
    android:layout_width="0dp"
    android:layout_height="match_parent">

</LinearLayout>

当我运行应用程序时,由于 commit() 调用而出现异常,导致当我删除 commit() 调用时未引发异常,并且无论如何这些行已成功创建并添加到层次结构中。

我得到以下异常 07-08 03:36:27.414: E/AndroidRuntime(835): java.lang.RuntimeException: Unable to start activity ComponentInfo{io.raindance.kalimat/io.raindance.kalimat.test.KalimatActivity}: java.lang.IllegalArgumentException:没有为片段 CellFragment {4103c790 #1 id=0x7f050005} 找到 id 0x7f050005 的视图

我一直在寻找这个问题的原因和解决方案 2 天。

Activity需要创建(并保存其状态)才能执行 a ,FragmentTransaction否则您将收到异常。请尝试执行您的交易onActivityCreated
