android-我只想将裁剪后的图像保存到图库中.但会保存原始的完整图像.如何仅保存裁切后的图像？

public class ImageCroppMainActivity extends Activity implements OnClickListener{

final int CAMERA_CAPTURE = 1;

//keep track of cropping intent

final int PIC_CROP = 2;

//captured picture uri

private Uri picUri;

@Override

    //handle button clicks

    captureBtn.setonClickListener(this);

    Button browseBtn = (Button)findViewById(R.id.browse_btn);

    //handle button clicks

    browseBtn.setonClickListener(this);

}



public void onClick(View v) {

    if (v.getId() == R.id.capture_btn) {   

        try {

Intent(MediaStore.ACTION_IMAGE_CAPTURE);

            //we will handle the returned data in onActivityResult

startActivityForResult(captureIntent, CAMERA_CAPTURE);

}

catch(ActivityNotFoundException anfe){

//display an error message

AngularJS $ rootScope$ broadcast在app.run中不起作用

myApp.run(['AuthDataSvc','$rootScope',function (AuthDataSvc,$rootScope) {    
    AuthDataSvc.getAuth().then(function(Token){
        $rootScope.$broadcast('Token',Token);
    },function(status){
        console.log(status);
    });     
}]);

AngularJS $ rootScope。$ broadcast在app.run中不起作用

我在AngularJS
.run下有以下代码，该代码在我的本地开发计算机上可以正常运行，但在上传到客户端服务器后将无法工作…经过几次测试，很明显，在加载控制器时，事件并未尚未触发，因此取决于此事件的控制器中的大多数功能均无法正常工作。有人可以告诉我我在做什么错以及如何解决吗？谢谢

myApp.run([''AuthDataSvc'', ''$rootScope'', function (AuthDataSvc, $rootScope) {        AuthDataSvc.getAuth().then(function(Token){        $rootScope.$broadcast(''Token'', Token);    }, function(status){        console.log(status);    });     }]);

答案1

你总是要有一个比赛条件。我可以选择几种替代方法：

1）使用服务。我并不是这个选项的忠实支持者，因为它会导致产生Spaghetti代码。大多数情况下，您不希望控制器在登录之前运行。我喜欢选项2。

 myApp.run([''AuthDataSvc'', ''$rootScope'', function (AuthDataSvc, $rootScope) {        AuthDataSvc.getAuth(); /* no op we will use the service to determine logged in */}]);/* inside a controller */if(AuthDataSvc.isLoggedIn()){      //do something.}

2）使用route.resolve。解析是在路由上定义的，并且只有在将诺言设置为已解析后，Controller才会加载。我为您展示了一个示例ui-router，ng-route您需要选择毒药。如果您不使用ui-router，则应考虑使用。

/* app.config ... route config.. */var waitForLogon = {      UserToken: ["AuthDataSvc", function (AuthDataSvc) {         return AuthDataSvc.logon();      }]};//this is for ng-route $routeProvider   .when(''/Book/:bookId'', {      templateUrl: ''--'',      controller: ''MyCtrl'',      resolve: waitForLogon   })//this is for ui-router $stateProvider     .state(''me'', {            templateUrl: ''--'',            controller: ''MeCtrl'',            resolve: waitForLogon })

/* controller */ angular.module(''yourapp'')    .controller(''MyCtrl'', ["UserToken", ... , function(UserToken){                  //User Token will always be here when your Ctrl loads.   });

/* service code -- */angular.module(''yourapp'')    .service(''AuthDataSvc'', ["LogonModel", "$q", function(LogonModel, $q) {        this._q = null;        var that = this;        this._doAuth = function(){           this.getAuth().then(function(Token){ that._q.resolve(Token) }, function(error){that._q.reject(error);}        };        this.logon = function () {            if(!this._q){              this._q = $q.defer();               this._doAuth();// <-current auth do here, and resolve this._q when done            }            return this._q.promise;        };    });

AngularJS $rootScope.$broadcast在app.run中不起作用

myApp.run(['AuthDataSvc','$rootScope',function (AuthDataSvc,$rootScope) {    
    AuthDataSvc.getAuth().then(function(Token){
        $rootScope.$broadcast('Token',Token);
    },function(status){
        console.log(status);
    });     
}]);

myApp.run(['AuthDataSvc',$rootScope) {    
    AuthDataSvc.getAuth(); /* no op we will use the service to determine logged in */
}]);


/* inside a controller */
if(AuthDataSvc.isLoggedIn()){
      //do something.
}

/* app.config ... route config.. */
var waitForlogon = {
      UserToken: ["AuthDataSvc",function (AuthDataSvc) {
         return AuthDataSvc.logon();
      }]
};

//this is for ng-route
 $routeProvider
   .when('/Book/:bookId',{
      templateUrl: '--',controller: 'MyCtrl',resolve: waitForlogon
   })


//this is for ui-router 
$stateProvider
     .state('me',{
            templateUrl: '--',controller: 'MeCtrl',resolve: waitForlogon
 })

/* controller */
 angular.module('yourapp')
    .controller('MyCtrl',["UserToken",...,function(UserToken){
                  //User Token will always be here when your Ctrl loads.
   });

/* service code -- */
angular.module('yourapp')
    .service('AuthDataSvc',["logonModel","$q",function(logonModel,$q) {
        this._q = null;
        var that = this;
        this._doAuth = function(){
           this.getAuth().then(function(Token){ that._q.resolve(Token) },function(error){that._q.reject(error);}
        };
        this.logon = function () {
            if(!this._q){
              this._q = $q.defer();
               this._doAuth();// <-current auth do here,and resolve this._q when done
            }
            return this._q.promise;
        };
    });
