Android select video from gallery API(Android 從相簿選擇影片)

 

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import androidx.activity.result.ActivityResult;
import androidx.activity.result.ActivityResultCallback;
import androidx.activity.result.ActivityResultLauncher;
import androidx.activity.result.contract.ActivityResultContracts;
import androidx.appcompat.app.AppCompatActivity;



public class Get_Video {

    public  interface  ActionListener{
        public  void get_video_uri(Uri video_uri);
        public  void cancel_select();
    }
    public  ActionListener actionListener=null;
    private ActivityResultLauncher<Intent> get_Launcher;

    public  Get_Video(AppCompatActivity activity){


        get_Launcher = activity.registerForActivityResult(
                new ActivityResultContracts.StartActivityForResult(),
                new ActivityResultCallback<ActivityResult>() {
                    @Override
                    public void onActivityResult(ActivityResult result) {

                        if (result.getResultCode() == Activity.RESULT_OK) {

                            Intent data = result.getData();
                            Uri   selectedVideoUri = data.getData();
                            if(actionListener!=null)
                                actionListener.get_video_uri(selectedVideoUri);

                        }else{

                            if(actionListener!=null)
                                actionListener.cancel_select();


                        }


                    }
                });




        
    }

    public void   select_video(){

        Intent intent = new Intent();
        intent.setType("video/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        get_Launcher.launch(intent);

    }
    
}

使用方法:

videoView=findViewById(R.id.video_view);
get_video=new Get_Video(this);
get_video.actionListener=new Get_Video.ActionListener() {
    @Override
    public void get_video_uri(Uri video_uri) {

        videoView.setVideoURI(video_uri);
        videoView.start();
    }

    @Override
    public void cancel_select() {

    }
};
get_video.select_video();
