Android 打开相册选择单张图片实现代码

                以下就是如何在应用中打开图库并选择一张图片进行应用，代码很简单，注释很详细。

实现代码：

btn8.setOnClickListener(new View.OnClickListener() {      @Override      public void onClick(View view) {        Intent intent = new Intent();                intent.setType("image        intent.setAction(Intent.ACTION_GET_CONTENT);                startActivityForResult(intent, 1);//Intent intent = new Intent(Intent.ACTION_PICK, Android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);// startActivityForResult(intent, RESULT);      }    }); @Override  protected void onActivityResult(int requestCode, int resultCode, Intent data) {    if (resultCode == RESULT_OK) {      Uri uri = data.getData();      Log.e("uri", uri.toString());      ContentResolver cr = this.getContentResolver();      try {        Bitmap bitmap = BitmapFactory.decodeStream(cr.openInputStream(uri));                iv8.setImageBitmap(bitmap);      } catch (FileNotFoundException e) {        Log.e("Exception", e.getMessage(), e);      }    }    super.onActivityResult(requestCode, resultCode, data);  }
