拿到能打开指定类型文件的应用程序
Intent it = new Intent();it.setType("image/*")List<ResolveInfo> ra = this.getPackageManager().queryIntentActivities(it,0); for(int i=0;i<ra.size();i++){ ActivityInfo ai = ra.get(i).activityInfo; Drawable icon = ai.loadIcon(this.getPackageManager()); //图标 String label = ai.loadLabel(this.getPackageManager()).toString(); //名称 ComponentName c = new ComponentName(ai.applicationInfo.packageName, ai.name); //组件名,可以通过startActivity()打开此应用 }如果你要打开其他的媒体资源:video or audio
指定相应的Type即可!
