android - 通过 Intent 将图库图像传递给另一个 Activity

Question

我需要使用该图像的路径将图像从画廊发送到另一个 Activity ，但没有任何反应......帮帮我......这是代码..

        protected void onActivityResult(int requestCode, int resultCode, Intent data)
        {
             super.onActivityResult(requestCode, resultCode, data);
           if(requestCode==RESULT_LOADIMAGE&&resultCode==RESULT_OK&&null!=data)
       {
        Uri selectedImages=data.getData();
        String[] filePathColon={MediaStore.Images.Media.DATA};
        Cursor cursr=getContentResolver().query(selectedImages, filePathColon, null, null, null);
        cursr.moveToFirst();
        int columnindex=cursr.getColumnIndex(filePathColon[0]);
        String picturepath=cursr.getString(columnindex);
        cursr.close();

    Intent  intent= new Intent(MainActivity.this,SecondActivity.class);
      intent.putExtra("imagePath",filePathColon );
        startActivity(intent);

       }
   }

第二个 Activity 代码是

    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_second);
    img=(ImageView)findViewById(R.id.imageView1);


       getData();

       }

      private void getData(){
    String ps=getIntent().getStringExtra("imagepath");

    img.setImageBitmap(BitmapFactory.decodeFile(ps));

}   

Answer 1

intent.putExtra("imagePath",filePathColon );

应该是

intent.putExtra("imagePath",picturepath);

因为 filepathcolon 指的是列索引而 picturepath 指的是 URI

并使用它

String ps=getIntent().getStringExtra("imagePath"); //it should be same as you send it
