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

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

            }

        }

    }
}
}
