我有一个名为 activity_update.xml 的布局文件。这是代码：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin" >

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/have_class"
    android:textAppearance="?android:attr/textAppearanceLarge" />

<RadioGroup
    android:id="@+id/rgHaveClass"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="@dimen/marginLeft"
    android:layout_marginRight="@dimen/marginRight"
    android:gravity="center"
    android:orientation="horizontal" >

    <RadioButton
        android:id="@+id/rClassNo"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="@string/no"
        android:textSize="?android:attr/textAppearanceMedium" />

    <RadioButton
        android:id="@+id/rClassYes"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:checked="true"
        android:text="@string/yes"
        android:textSize="?android:attr/textAppearanceMedium" />
</RadioGroup>

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="@dimen/paddingTop"
    android:text="@string/miss_class"
    android:textAppearance="?android:attr/textAppearanceLarge" />

<RadioGroup
    android:id="@+id/rgMissClass"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="@dimen/marginLeft"
    android:layout_marginRight="@dimen/marginRight"
    android:gravity="center"
    android:orientation="horizontal" >

    <RadioButton
        android:id="@+id/rMissYes"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="@string/yes"
        android:textSize="?android:attr/textAppearanceMedium" />

    <RadioButton
        android:id="@+id/rMissNo"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:checked="true"
        android:text="@string/no"
        android:textSize="?android:attr/textAppearanceMedium" />
</RadioGroup> </LinearLayout>

这是 ActivityUpdate 类：

public class ActivityUpdate extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_update);
}}

我在 onCreate() 中使用了 setContentView(R.layout.activity_update)，它在 Gingerbread 和 Jellybean 上都显示了 ANR。

我还尝试将资源名称更改为另一个布局资源，它工作正常。eclipse 也没有显示任何错误或警告，它确实可以编译。有人可以指出我的xml中的任何错误。谢谢一堆。:)

顺便说一句，得到了 logcat 输出：

问题在于textSize每个RadioButton. 它应该是textAppearance

改变

android:textSize="?android:attr/textAppearanceMedium"

至

android:textAppearance="?android:attr/textAppearanceMedium"

但是，如果您希望以像素为单位设置文本大小，请使用textSize如下属性：

android:textSize="@dimen/text_size_medium"

在哪里dimens.xml，提到

<dimen name="text_size_medium">20sp</dimen>

我想是因为你的 RadioButton，都有

android:layout_width="match_parent"

和

android:layout_weight="1"

全部更改为

android:layout_width="0dp"

希望这有帮助。
