解决方法
提高动作意图为ACTION_GET_CONTENT,并将类型设置为“image / *”.这将启动照片选择器活动.当用户选择图像时,可以使用onActivityResult回调来获取结果.
就像是：
Intent photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent,1);
protected void onActivityResult(int requestCode,int resultCode,Intent data)
{
super.onActivityResult(requestCode,resultCode,data);
if (resultCode == RESULT_OK)
{
Uri chosenImageUri = data.getData();
Bitmap mBitmap = null;
mBitmap = Media.getBitmap(this.getContentResolver(),chosenImageUri);
}
}
