之前代码运行正常,但是当我将支持库更新到24时,它在显示警告对话框时崩溃了。 由于最近更新了,无法找到任何帮助。

代码:

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

logcat的:

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]]

支持库是:

    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'

答案 0 :(得分:1)

我认为您的导入存在问题。

例外:

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

表示无法找到DialogTitle,但我没有看到DialogTitle代码中的任何位置。

因此,如果您在项目的任何位置进行任何名为android.support.v7.internal.widget.DialogTitle的导入,请将其删除。

您需要为AlertDialog导入此内容:

 import android.app.AlertDialog;

而不是:

 import android.support.v7.app.AlertDialog;

导入此内容:

import android.app.AlertDialog;
