当android支持库更新为24时，AlertDialog构建器中崩溃 [英] Crash in AlertDialog builder when android support library updated to 24

问题描述

该代码以前运行良好，但是当我将支持库更新为24时，显示警报对话框时会崩溃. 找不到任何帮助，因为它最近已更新.

The code was working fine before, but when I updated support library to 24, It crashes when displaying alert dialog. Couldn't find any help as it is updated recently.

代码:

AlertDialog.Builder builderSingle;
builderSingle = new AlertDialog.Builder(mContext);
//set buttons and title code
builderSingle.show();

Logcat:

Caused by: java.lang.ClassNotFoundException: Didn't find class "android.support.v7.internal.widget.DialogTitle" on path: DexPathList[[zip file "/data/app/com.abc-2/base.apk"],nativeLibraryDirectories=[/data/app/com.abc-2/lib/arm, /data/app/com.abc-2/base.apk!/lib/armeabi-v7a, /vendor/lib, /system/lib]]

支持库为:

    compile('com.android.support:recyclerview-v7:24.0.0') {
        exclude group: 'com.android.support', module: 'support-v4'
    }
    compile('com.android.support:support-v4:24.0.0') {
        force = true
    }
    compile 'com.android.support:appcompat-v7:24.0.0'
    compile 'com.android.support:design:24.0.0'

推荐答案

我认为您的导入存在一些问题.

例外:

java.lang.ClassNotFoundException: Didn't find class "android.support.v7.internal.widget.DialogTitle"

说它找不到DialogTitle，但是我在代码中的任何地方都没有看到DialogTitle.

says it is unable to find DialogTitle but i am not seeing DialogTitle any where in your code.

因此，如果您在项目中的任何位置都有任何名为android.support.v7.internal.widget.DialogTitle的导入，则将其删除.

So if you are having any import called android.support.v7.internal.widget.DialogTitle any where in your project then remove it.

您需要将其导入AlertDialog:

You need to import this for your AlertDialog:

 import android.app.AlertDialog;

代替此:

 import android.support.v7.app.AlertDialog;
