android Intent.setType() 过滤图片,返回所有的文件类型

谁借莪１个温暖的怀抱￠ 2022-08-06 05:24 115阅读 0赞

我想在我的app中通过Intent从启动的应用程序中刚抓取图片

我尝试使用如下代码：

Intent intent = new Intent("android.intent.action.GET_CONTENT");
        intent.addCategory("android.intent.category.OPENABLE");
        intent.setType("image/*");

### 处理方法 ###

id.os.Bundle;
     
     
     
    public class StackOverflowAppActivity extends Activity {
      
        private final int PICK_IMAGE = 0;
     
     
     
        /** Called when the activity is first created. */
      
        @Override
      
        public void onCreate(Bundle savedInstanceState) {
      
            super.onCreate(savedInstanceState);
      
            setContentView(R.layout.main);
     
     
     
            Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
      
            startActivityForResult(i, PICK_IMAGE);
     
     
     
     
        }
     
     
     
        @Override
      
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
      
            super.onActivityResult(requestCode, resultCode, data);
     
     
     
            switch (requestCode) {
     
     
     
            case PICK_IMAGE:
      
                if (resultCode == RESULT_OK) {
      
                    // do your thing
      
                }
      
            }
      
        }
    }
    }
