android 应用详情,Android 跳转应用市场的应用详情页

工具类：

public static Intent getIntent(Context paramContext)

{

StringBuilder localStringBuilder = new StringBuilder().append("market://details?id=");

String str = paramContext.getPackageName();

localStringBuilder.append(str);

Uri localUri = Uri.parse(localStringBuilder.toString());

return new Intent("android.intent.action.VIEW", localUri);

}

//直接跳转不判断是否存在市场应用

public static void start(Context paramContext, String paramString)

{

Uri localUri = Uri.parse(paramString);

Intent localIntent = new Intent("android.intent.action.VIEW", localUri);

localIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

paramContext.startActivity(localIntent);

}

public static boolean judge(Context paramContext, Intent paramIntent)

{

List localList = paramContext.getPackageManager().queryIntentActivities(paramIntent,PackageManager.GET_INTENT_FILTERS);

if ((localList != null) && (localList.size() > 0)){

return false;

}else{

return true;

}

}

实现跳转：

Intent i = GetUri.getIntent(GetMarketActivity.this);

boolean b = GetUri.judge(GetMarketActivity.this, i);

if(b==false)

{

startActivity(i);

}
