即使内容不可见,如何在Android上截取整个活动的屏幕截图？防爆.截取完整聊天的截图然后生成图像文件？

我也想要截图隐形区域.

谢谢

我一直在尝试将 Camera2 api 集成到我的应用程序中。当我从纵向模式切换到横向模式时，它会引发异常

这是我的代码：

 private void getUserData(){
    //create Retrofit instance
    Retrofit.Builder builder = new Retrofit.Builder()
            .baseUrl(Constants.BASE_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .addCallAdapterFactory(RxJava2CallAdapterFactory.create());

    Retrofit retrofit = builder.build();

    //get client & call object for the request
    APIService userService = retrofit.create(APIService.class);

    Map<String, Object> map = new HashMap<>();
    map.put("device_id", Utils.GetDeviceID(DashboardActivity.this));

    Call call = userService.getUser(map);

    //execute network request
    call.enqueue(new Callback() {
        @Override
        public void onResponse(Call call, Response response) {
            if(response.isSuccessful() && response.body() != null){
                response.body();
                UserDataManager.$().setUserDataResponse(new com.google.gson.Gson().toJson(response.body()));
                if(UserDataManager.$().getUserData() != null){
                    Log.d(TAG, "USER ID: " + UserDataManager.$().getUserData().getId());
                }
            }
        }

        @Override
        public void …
