我可以打开图库并获取图库的路径= content:// media/external/images/media/2但无法在imageview中解码这是我的代码

public void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState); 的setContentView(R.layout.main);

            b=(Button) findViewById(R.id.Button01);
            b.setOnClickListener(new OnClickListener() {

                public void onClick(View arg0) {

                    // in onCreate or any event where your want the user to
                    // select a file
                    Intent intent = new Intent();
                    intent.setType("image/*");
                    intent.setAction(Intent.ACTION_GET_CONTENT);
                    startActivityForResult(intent,IMAGE_PICK);
                }
            });
        }

        //UPDATED
        public void onActivityResult(int requestCode, int resultCode, Intent data) {
            if (resultCode == RESULT_OK) {
                if (requestCode == IMAGE_PICK) {
                    Uri selectedImageUri = data.getData();


                    //OI FILE Manager
                    filemanagerstring = selectedImageUri.getPath();

                    //MEDIA GALLERY
                    selectedImagePath = getPath(selectedImageUri); …

我使用共享首选项来存储密码,但是当我的应用程序启动时再次询问首选项值.我希望一旦我输入了首选项密码就应该修复它应该一次又一次地问我.
