Android - java.lang.reflect.InvocationTargetException 调用 dialog.show()

Question

尝试在 Nexus 5 模拟器（API 24 / Google API）上运行我的代码（如下）时出现上述异常...

我看到了类似问题的答案，建议将 SplashActivity.this 传递给 Dialog 构造函数，而不是传递 getApplicationContext() - 但我已经传递了一个活动实例。

有什么想法可能是错的吗？

我的代码！...

private boolean checkPlayServices() {
    GoogleApiAvailability googleAPI = GoogleApiAvailability.getInstance();
    int result = googleAPI.isGooglePlayServicesAvailable(this);
    if (result != ConnectionResult.SUCCESS) {
    if (googleAPI.isUserResolvableError(result)) {
        Dialog dialog = googleAPI.getErrorDialog(this, result, PLAY_SERVICES_RESOLUTION_REQUEST);
        dialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
        @Override
        public void onCancel(DialogInterface dialogInterface) {
            SplashActivity.this.finish();
        }
        });
        dialog.show();
    }
    return false;
    }
    return true;
}

Answer 1

下面的错误方式告诉你

java.lang.UnsupportedOperationException: 
   Failed to resolve attribute at index 6: TypedValue{t=0x2/d=0x101009b a=1}

这似乎是在尝试在您的目标设备上评估 ColorStateList 时发生的。因此，如果有任何 XML 属性与您的应用程序的 minSdk 存在差异，我会检查颜色定义。一般来说，执行 Lint 也可能会直接指出这样的错误，因为它非常适合查找这些东西（在命令行中使用 ./gradlew lint）。

Answer 2

感谢 Thomas Keller 在his answer 上的 cmets，我找到了解决方案。

基本上，我在v21\style.xml 文件中使用了自己的对话框样式：

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:alertDialogTheme">@style/MyAlertDialog</item>
    <item name="alertDialogTheme">@style/MyAlertDialog</item>
</style>

<style name="MyAlertDialog" parent="Theme.AppCompat.Dialog.Alert">
    <item name="colorAccent">?attr/colorAccent</item>
</style>

Google API 对话框尝试使用此样式，因此从我的 xml 中删除它已解决问题。

但是，我仍然想使用 MyAlertDialog（因为它的 colorAccent 值），所以有谁知道我必须添加什么颜色才能安抚 Google API 对话框（以及任何其他 Google/系统对话框)?
