onNewIntent 什么时候调用

2011-05-24 21:30 218 查看

protected void onNewIntent (Intent intent)

Since: API Level 1

This is called for activities that set launchMode to "singleTop" in their package, or if a client used the
FLAG_ACTIVITY_SINGLE_TOP
 flag when calling 
startActivity(Intent)
. In either case, when the activity is re-launched while at the top of the activity stack instead of a new instance of the activity being started, onNewIntent() will be called on the existing instance with the Intent that was used to re-launch it.

An activity will always be paused before receiving a new intent, so you can count on 
onResume()
 being called after this method.

Note that 
getIntent()
 still returns the original Intent. You can use 
setIntent(Intent)
 to update it to this new Intent.

在IntentActivity中重写下列方法:onCreate onStart onRestart  onResume  onPause onStop onDestroy  onNewIntent
一、其他应用发Intent,执行下列方法:
I/@@@philn(12410): onCreate
I/@@@philn(12410): onStart
I/@@@philn(12410): onResume

发Intent的方法:
Uri uri = Uri.parse("philn://blog.163.com");
Intent it = new Intent(Intent.ACTION_VIEW, uri);    
startActivity(it);

二、接收Intent声明:
 <activity android:name=".IntentActivity" android:launchMode="singleTask"
                  android:label="@string/testname">
             <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data android:scheme="philn"/>
            </intent-filter>
  </activity>

三、如果IntentActivity处于任务栈的顶端,也就是说之前打开过的Activity,现在处于
I/@@@philn(12410): onPause
I/@@@philn(12410): onStop 状态的话
其他应用再发送Intent的话,执行顺序为:
I/@@@philn(12410): onNewIntent
I/@@@philn(12410): onRestart
I/@@@philn(12410): onStart
I/@@@philn(12410): onResume
