Question

当我尝试在API 21之前的设备上运行我的应用程序时，我收到了这个奇怪的错误：

I/Choreographer: Skipped 39 frames!  The application may be doing too much work on its main thread.

实际上我没有得到ANR或者不幸的是你的应用程序停止了工作，应用程序默默地退出到主要活动。

我没有在我的应用程序中使用任何重量级图像，只有一个带有四个微调器的页面。

特别是，此行以红色突出显示：

E/dalvikvm: Could not find class 'android.widget.ThemedSpinnerAdapter', referenced from method android.support.v7.widget.AppCompatSpinner$DropDownAdapter.<init>

然而，由于我没有使用eclipse，我确信我使用gradle进行了正确的导入：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "projects.test.com.webviewtest"
        minSdkVersion 14
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'com.android.support:recyclerview-v7:23.1.1'
}

Answer 1

在我的情况下，通过在布局XML文件中删除{{1}}的使用来解决这个问题......也许这有助于其他人。

Answer 2

我在项目中解决了查找compileSdkVersion的问题。我有4个模块，其中3个用sdk 22编译，一个用sdk 23编译。

在我将所有这些内容更改为sdk 22后，问题解决了。所以我的建议是检查SDK版本，并为项目中的所有模块选择相同的编号。

干杯

Answer 3

我也遇到了与微调器相同的问题，它在某些设备上运行而在某些设备上没有运行。因为我放了setAdapter(null)。因此，它表现得像这样。而不是放ArrayList arrayList = new ArrayList(); spinner.setAdapter(new ArrayAdapter<String>(activity.this, android.R.layout.simple_dropdown_item_1line, arrayList)); 然后它将适用于所有设备。

Answer 4

在您的layout.xml中添加以下内容。...

     # xmlns:app="http://schemas.android.com/apk/res-auto"

确保在将listnerEvents设置为微调器的末尾，将数组列表设置为微调器，

快乐的编码.....
