[英]Starting the Main activity from another activity
I am trying to achieve following case on Android, but no success: 1) Launch Application (Launcher Activity which is a subclass of Base Activity). 我正在尝试在Android上实现以下情况,但没有成功:1)启动应用程序(Launcher Activity,它是Base Activity的子类)。 The Base Activity has code as follows:
基本活动的代码如下:
///This is in BaseActivity
@Override
public void onCreate(Bundle instance)
{
super.onCreate(instance);
//Config.isLoggedIn() is a static function.
if(! Config.isLoggedIn())
{
////Config.startLoginActivity is a static function
Config.startLoginActivity(this, getIntent());
finish();
}
}
The Config.startLoginActivity functions is defined as Config.startLoginActivity函数定义为
public static void startLoginActivity(final Context ctx, final Intent finishIntent)
{
Intent i = new Intent(ctx, ItemListActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.putExtra("FINISH_INTENT", finishIntent);
ctx.startActivity(i);
}
Now, the ItemListActivity contains a list of Items as {Item1, Item2, Item3}. 现在,ItemListActivity包含项列表,如{Item1,Item2,Item3}。 In ItemListActivity, I am saving the passed "finishIntent" as
在ItemListActivity中,我将传递的“ finishIntent”保存为
///This is ItemListActivity onCreate Method
if(getIntent().hasExtra("FINISH_INTENT"))
mFinishIntent = getIntent().getParcelableExtra("FINISH_INTENT");
and the onItemListSelected method is described as follows : 并且onItemListSelected方法描述如下:
@Override
public void onItemSelected(String id) {
Config.setLogInState(true);
if(mFinishIntent != null)
{
Log.i("ITEMLISTACTIVITY", "Class Name = " + mFinishIntent.getClass().getName());
Log.i("ITEMLISTACTIVITY", "Starting mFinishIntent Activity");
startActivity(mFinishIntent);
finish();
}
}
But the issue is the Main Activity is not being launched again, Android takes me to the home screen instead. 但是问题是没有再次启动Main Activity,Android将我带到了主屏幕。 While looking for a solution, I saw that Google I/O app has the same implementation and that works flawlessly but in my case it is not.
在寻找解决方案时,我发现Google I / O应用具有相同的实现,并且可以完美地工作,但就我而言,却并非如此。 I am unable to figure it out.
我无法弄清楚。 Please help.
请帮忙。
Thanks in Advance. 提前致谢。
Manifest File is as follows : 清单文件如下:
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.app.myapplication.ItemListActivity"
android:label="@string/app_name" >
</activity>
<activity
android:name="com.app.myapplication.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Ok Here is a quick help which works for 100 percent which I'm using not mostly but EVERYTIME! 好的,这里是一个快速帮助,它可以100%正常工作,我使用的不是大多数,而是每次! you must past it through intent and in your case here it is how it must look like.
您必须通过意图来克服它,并且在这种情况下,它必须是这样。
Intent intent = new intent(//name of your activity in which you are at the moment.this, //name of activity to which you want to go.class); Intent intent = new intent(//当前您所在的活动的名称。this,//您要进入的活动的名称.class); startActivity(intent);
startActivity(intent);
Hope this will help 希望这会有所帮助
