<activity android:name=".app.PersistentState"
android:label="@string/activity_persistent"
android:windowSoftInputMode="stateVisible|adjustResize"> //屏幕在出现软键盘情况下自适应大小
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.SAMPLE_CODE" />
</intent-filter>
</activity>

Intent intent = new Intent(ReorderFour.this, ReorderTwo.class);
intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
startActivity(intent);

ANDROID系统,如果该Activity有记录,则删除Stack中记录,然后再入stack放到最后。

int android.content. Intent .FLAG_ACTIVITY_REORDER_TO_FRONT = 131072 [0x20000]

public static final int FLAG_ACTIVITY_REORDER_TO_FRONT

Since: API Level 3

If set in an Intent passed to Context.startActivity() , this flag will cause the launched activity to be brought to the front of its task's history stack if it is already running.

For example, consider a task consisting of four activities: A, B, C, D. If D calls startActivity() with an Intent that resolves to the component of activity B, then B will be brought to the front of the history stack, with this resulting order: A, C, D, B. This flag will be ignored if FLAG_ACTIVITY_CLEAR_TOP is also specified.

Constant Value: 131072 (0x00020000)
