注册关闭Android应用程序 [英] Reg Closing the Android Application

问题描述

大家好，



我是Android应用程序开发的新手。我创建了一个简单的幻灯片应用程序并添加了一个mp3来播放背景。我正在使用Menu控件。

我有一个名为Exit的菜单项试图在用户点击这个项目时关闭应用程序。



我有以下代码来关闭应用程序。此代码关闭应用程序但不会停止在应用程序中运行的mp3。你能帮我解决这个问题吗？



先谢谢。

Hi All,

Am new to Android Application development. I have created a simple slideshow application and added a mp3 to play background. Am working with Menu control currently.
I have a menu item named "Exit" trying to close the application when user click this item.

I have below code to close the application. This code close the application but does not stop the mp3 which runs in the application. Could you please help me to resolve this issue.

Thanks in Advance.

public boolean onOptionsItemSelected(MenuItem item) {
		TextView lblDateTime = (TextView) findViewById(R.id.lblDateTime);
		 lblDateTime.setText(item.getItemId()); 
		 boolean result = false;
	  switch (item.getItemId()) {
	        case R.id.mnabout:
	   	     lblDateTime.setText("About selected"); 
	   	  result = true;
	   	  break;
	        case R.id.mnexit:
	        	//lblDateTime.setText("exit selected"); 
	        	result = true;
	        	this.finish();
	        	 break;
	        default:
	        	result = super.onOptionsItemSelected(item);
	        	 break;
	    }
		 return result;
	}

问候，

推荐答案

试试这个：

try this:

public boolean onOptionsItemSelected(MenuItem item) {
            TextView lblDateTime = (TextView) findViewById(R.id.lblDateTime);
             lblDateTime.setText(item.getItemId());
             boolean result = false;
          switch (item.getItemId()) {
                case R.id.mnabout:
                 lblDateTime.setText("About selected");
              result = true;
              break;
                case R.id.mnexit:
                    //lblDateTime.setText("exit selected");

// mediaplayer is object of MediaPlayer class as you declared for playing mp3

              if(mediaplayer!=null && mediaplayer.isplaying()){
                    mediaplayer.stop();
                }



                    result = true;
                    this.finish();
                     break;
                default:
                    result = super.onOptionsItemSelected(item);
                     break;
            }
             return result;
        }
