Question

我正在为Android构建一个phonegap应用程序，需要一种方法来使用javascript从应用程序www目录中包含的.jpg设置壁纸。我将如何构建一个与我的phonegap应用程序www文件夹中的资源配合使用的phonegap插件？

Answer 1

只需从资产文件夹中读取文件。带插件

    import java.io.IOException;

    import org.apache.cordova.api.Plugin;
    import org.apache.cordova.api.PluginResult;
    import org.apache.cordova.api.PluginResult.Status;
    import org.json.JSONArray;

    import android.app.WallpaperManager;
    import android.content.Context;

    public class testPlugin extends Plugin {
        public final String ACTION_SET_WALLPAPER = "setWallPaper";
        @Override
        public PluginResult execute(String action, JSONArray arg1, String callbackId) {
            PluginResult result = new PluginResult(Status.INVALID_ACTION);
            if (action.equals(ACTION_SET_WALLPAPER)) {
                WallpaperManager wallpaperManager = WallpaperManager.getInstance((Context) this.ctx);
                try {
                  InputStream bitmap=null;
                   bitmap=getAssets().open("www/img/" + arg1.getString(0));//reference to image folder
                    Bitmap bit=BitmapFactory.decodeStream(bitmap);
                    wallpaperManager.setBitmap(bit);
                    result = new PluginResult(Status.OK);
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                    result = new PluginResult(Status.ERROR, e.getMessage());
                }
            }
            return result;
        }
    }

这是javascript文件test.js

var TestPlugin = function () {};

TestPlugin.prototype.set = function (ms, successCallback, failureCallback) {  
//  navigator.notification.alert("OMG");
    return cordova.exec(successCallback, failureCallback, 'testPlugin', "setWallPaper", [ms]);
};

PhoneGap.addConstructor(function() {
    PhoneGap.addPlugin("test", new TestPlugin());
})

和主文件调用带有imagefilename的插件

window.plugins.test.set("imageFileName.jpg",
        function () { 
            navigator.notification.alert("Set Success");    
        },
        function (e) {
            navigator.notification.alert("Set Fail: " + e);
        }
    );

;

使用Android设备权限

<uses-permission android:name="android.permission.SET_WALLPAPER" />

和plugin.xml

<plugin name="testPlugin" value="com.android.test.testPlugin"/>

来自www资产的Phonegap设置壁纸？ Android的
