Question

我有一个底栏。它有一个相机图标。当我点击图标时。它向我展示了一个对话框。该对话框有3个按钮。这些是相机请求，图库请求和取消。我带着照相机请求拍照，这是我过去的意图。然后我按下提交按钮（在模拟器默认按钮中）。但它给了我一个例外。我的目的是：我想将拍摄的照片发送给其他活动。然后将其设置为我的图像视图。我怎么能这样做？

这是我的提交按钮： enter image description here

这是我的代码：

  private static final int CAMERA_REQUEST = 1888;
   private void openCamera() {

        Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(takePicture, CAMERA_REQUEST);


        try {
           /* camera.takePicture();*/
            dialog.dismiss();
        }catch (Exception e){
            e.printStackTrace();
        }

    }

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);


       switch (requestCode){
           case GALLERY_REQUEST : if(resultCode == RESULT_OK){   //gallery için 1
               Uri selectedImage = data.getData();
            //   deneme.setImageURI(selectedImage);
           }break;
           case CAMERA_REQUEST : if (resultCode == RESULT_OK){

              Uri selectedImage = data.getData();
           Intent i = new Intent(bottom_bar.this , fotograf_cekildikten_sonra_kaydet_iptal_yeri.class);
           i.putExtra("dene " ,selectedImage);
         startActivity(i);



           }

       }

我的其他活动：

 setContentView(R.layout.fotograf_cekildikten_sonra_kaydet_iptal_yeri);

    Bundle extras = getIntent().getExtras();
    Uri uri = extras.getParcelableExtra("dene");
    ımageView = (ImageView)findViewById(R.id.telefon_arama_ImageView);

    ımageView.setImageResource(uri);

意图不用于传递大数据。它是您的流程（应用程序）或IPC中的消息传递机制。如果您尝试传递大数据你可能会得到一个TransactionTooLargeException。你可以做的是你可以将照片保存到本地文件系统，然后将该照片的uri传递给通过Intent的其他活动。以下是如何执行此操作的官方指南： photobasics
