Question

[这是我的代码。请提供完整的代码。重新启动应用程序后应显示已接收的图像。谢谢] [1]

     @Override
public void onActivityResult(int requestCode, int resultCode,  Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
        Uri uri = data.getData();
        try {Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
            ImageView imageView = (ImageView) findViewById(R.id.imageView2);
            imageView.setImageBitmap(bitmap);
            String[] filePathColon={MediaStore.Images.Media.DATA};
            Cursor cursr=getContentResolver().query(uri, filePathColon, null, null, null);
            cursr.moveToFirst();
            int columnindex=cursr.getColumnIndex(filePathColon[0]);
            final String picturepath=cursr.getString(columnindex);
            cursr.close();
            b1= (Button) findViewById(R.id.button);
            b1.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Intent  intent= new Intent(edit_student.this,student.class);
                    intent.putExtra("imagePath",picturepath );
                    startActivity(intent);}});
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

将图像Uri发送到第二个活动，如下所示：

@override
public void onClick(View v){
Intent intent = new Intent(getApplicationContext(),student.class);
intent.putParceleableExtra("imageUri",uri);
startActivity(intent);

}

在你的SecondActivity onCreate（）获取意图并获取uri，从uri创建一个位图对象并将其设置为图像视图。

Uri retreivedUri = getIntent().getParceleableExra("imageUri");

在Android中，如何将图像从一个活动发送到另一个从图库中选择的活动？
