打開警告對話框打開的Android

Question

下載或視頻我已經在我的活動添加了這個條件

else if (url.contains("googlevideo.com")) { 
Intent intent = new Intent(Intent.ACTION_VIEW); 
intent.setDataAndType(Uri.parse(url), "video/*"); 
startActivity(intent); 

在那裏我有打開Dilog，可以幫助用戶選擇下載/觀看

在哪裏下載開始從該網址下載

和觀看按鈕開始以視頻形式打開，作爲defult的代碼。

Answer 1

密碼提示：

AlertDialog.Builder builder = new AlertDialog.Builder(this); 
    //builder.setTitle(" MY_TEXT"); 
    builder.setMessage("Would you like to see a video?") 
    .setView(checkBoxView) 
    .setCancelable(false) 
    .setPositiveButton("Yes", new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int id) { 
      //Start the movie 
      startVideo(); 
      dialog.cancel(); 
     } 
    }) 
    .setNegativeButton("No", new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int id) { 
      dialog.cancel(); 
     } 
    }).show().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND); 

代碼以打開視頻：

getWindow().setFormat(PixelFormat.TRANSLUCENT); 
final VideoView videoHolder = new VideoView(this); 
//if you want the controls to appear 
videoHolder.setMediaController(new MediaController(this)); 
Uri video = Uri.parse("android.resource://" + getPackageName() + "/" 
     + R.raw.documentariesandyou); //do not add any extension 
//if your file is named sherif.mp4 and placed in /raw 
//use R.raw.sherif 
videoHolder.setVideoURI(video); 
setContentView(videoHolder); 
videoHolder.setOnCompletionListener(new MediaPlayer.OnCompletionListener() { 

    @Override 
    public void onCompletion(MediaPlayer mp) { 
     //exits video! 
     videoHolder.stopPlayback(); 
     mp.release(); 
     finish(); 
    } 
}); 
videoHolder.start();
