android - 在 gradle 中声明 android.support.v7.app

Question

我对 AppCompat 有疑问和 Gradle ，第一个问题是我的应用只有一个 Gradle对于 module ，并且没有 Gradle对于像我在下面显示的图片这样的应用程序
我在我的其他应用程序中有 2 个 gradles，如果它的重要项目是使用 eclipse 编写的，那么我迁移到 android studio:



第二个是当我运行我的一项 Activity 时出现错误

这是我的导致错误的 Activity 代码:

 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_color);
    final ImageView imgbck= (ImageView) findViewById(R.id.imageView4);
    ColorPickerDialogBuilder
            .with(getApplicationContext())
            .setTitle("Choose color")
            //.initialColor(currentBackgroundColor)
            .wheelType(ColorPickerView.WHEEL_TYPE.FLOWER)
            .density(12)
            .setOnColorSelectedListener(new OnColorSelectedListener() {
                @Override
                public void onColorSelected(int selectedColor) {
                   // toast("onColorSelected: 0x" + Integer.toHexString(selectedColor));
                }
            })
            .setPositiveButton("ok", new ColorPickerClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int selectedColor, Integer[] allColors) {
                    imgbck.setBackgroundColor(selectedColor);
                }
            })
            .setNegativeButton("cancel", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                }
            })
            .build()
            .show();
}}

我的 gradle 内容也在这里:

allprojects {
repositories {
    maven { url "https://jitpack.io" }
}
}
buildscript {
repositories {
    maven { url "https://jitpack.io" }
    mavenCentral()


}
dependencies {

    classpath 'com.android.tools.build:gradle:1.5.0'
}
}
apply plugin: 'com.android.application'
configurations {
 all*.exclude group: 'com.android.support', module: 'support-v4'
}
dependencies {
compile 'com.github.QuadFlask:colorpicker:0.0.10'

compile 'com.android.support:appcompat-v7:23.1.1'

}

android {
compileSdkVersion 23
buildToolsVersion '23.0.1'
sourceSets {
    main {
        manifest.srcFile 'AndroidManifest.xml'
        java.srcDirs = ['src']
        resources.srcDirs = ['src']
        aidl.srcDirs = ['src']
        renderscript.srcDirs = ['src']
        res.srcDirs = ['res']
        assets.srcDirs = ['assets']
    }

    // Move the tests to tests/java, tests/res, etc...
    instrumentTest.setRoot('tests')

    // Move the build types to build-types/<type>
    // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
    // This moves them out of them default location under src/<type>/...    which would
    // conflict with src/ being used by the main source set.
    // Adding new build types or product flavors should be accompanied
    // by a similar customization.
    debug.setRoot('build-types/debug')
    release.setRoot('build-types/release')
}
defaultConfig {}
productFlavors {
}
buildTypes {
}

我已经为我的项目添加了 appcompact，但我认为该错误与 app compact 不知何故有关。

Answer 1

你的 Logcat 抛出

 java.lang.NoClassDefFoundError: android.support.v7.app.AppCompatDelegateImplV14

您应该删除 module: 'support-v4'
最后

    configurations {
        all*.exclude group: 'com.android.support'
}

那么 Clean-Rebuild-Sync 你的项目。

可以去掉，不需要

 configurations {
 all*.exclude group: 'com.android.support', module: 'support-v4'
}
