Android实现软件列表的点击启动另外一个程序功能【附demo源码下载】

public class AppListView extends LinearLayout implements OnItemClickListener{
  private final static String TAG = "AppListView";
  private ListView mListView;
  private TextView mTvTitle;
  private List mAppList;
  private Context mContext;
  private LayoutInflater mInflater;
  private PackageManager mPacManager;
  public AppListView(Context context, AttributeSet attrs) {
    super(context, attrs);
    init(context);
  }
  public AppListView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    init(context);
  }
  public AppListView(Context context)
  {
    super(context);
    init(context);
  }
  private void init(Context c)
  {
    mCOntext= c;
    mInflater = (LayoutInflater)c.getSystemService
         (Context.LAYOUT_INFLATER_SERVICE);
    this.addView(mInflater.inflate(R.layout.activity_main,null,false));
    mListView = (ListView)this.findViewById(R.id.listView);
    mTvTitle  = (TextView)this.findViewById(R.id.title);
    loadAppData();
    mListView.setAdapter(new MyAdapter(c));
    mListView.setOnItemClickListener(this);
    Log.d(TAG, "一共"+mAppList.size());
  }
  // 加载应用软件数据 软件名称，包名，对应的图标等等
  private void loadAppData()
  {
    if(mAppList != null){
      mAppList.clear();
    }else{
      mAppList = new ArrayList();
    }
    mPacManager = mContext.getPackageManager();
    List packages = mPacManager.getInstalledPackages(0);
    for(int i=0; i arg0, View arg1, int arg2, long arg3) {
    Toast.makeText(mContext, arg2+"", Toast.LENGTH_SHORT).show();
    // 获取本次item的包名
    String packName = mAppList.get(arg2).packageName;
    // 启动此程序
    Intent intent = mPacManager.getLaunchIntentForPackage(packName);
    mContext.startActivity(intent);
  }
  // 软件载体
  public class AppInfo {
    // 软件名称
    public String appName="";
    // 软件包名
    public String packageName="";
    // 软件图标
    public Drawable appIcon=null;
  }
}
