[转发]android界面研究 ：Activity的Title设置

1、改变标题内容：requestWindowFeature?(Window.FEATURE_NO_TITLE);?

3、隐藏标题和最上面的电池电量及信号栏（全屏）：

Java代码?

1. public???void??setFullscreen()?{??????
2. ????????????requestWindowFeature(Window.FEATURE_NO_TITLE);??????
3. ????????????getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,??????
4. ????????????????????WindowManager.LayoutParams.FLAG_FULLSCREEN);??????
5. ????????}???

Java代码?

1. public?void?setFullscreen()?{??????
2. ????????????requestWindowFeature(Window.FEATURE_NO_TITLE);??????
3. ????????????getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,??????
4. ????????????????????WindowManager.LayoutParams.FLAG_FULLSCREEN);??????
5. ????????}???

?4、自定义标题：

Java代码?

1. protected???void??onCreate(Bundle?savedInstanceState)?{??
2. ??super?.onCreate(savedInstanceState);??????
3. //预先设置允许改变的窗口状态，需在?setContentView?之前调用，否则设置标题时抛运行时错误。???
4. ??requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);?????
5. ??setContentView(R.layout.custom_title);?????
6. //标题区域可设置为?layout?，如此可以有丰富的展现方式????
7. ??
8. ??getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,??????
9. ???R.layout.custom_title_1);???
10. }??

Java代码?

1. protected?void?onCreate(Bundle?savedInstanceState)?{??
2. ??super.onCreate(savedInstanceState);??????
3. //预先设置允许改变的窗口状态，需在?setContentView?之前调用，否则设置标题时抛运行时错误。??
4. ??requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);?????
5. ??setContentView(R.layout.custom_title);?????
6. //标题区域可设置为?layout?，如此可以有丰富的展现方式???
7. ??
8. ??getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,??????
9. ???R.layout.custom_title_1);???
10. }??

?res\layout\custom_title_1.xml 包含一个TextView 用于显示标题。Android可以把标题做为一个layout来展示，具有很好的扩展性。

?

Java代码?

1. <RelativeLayout?xmlns:android=?"http://schemas.android.com/apk/res/android"??android:id=?"@+id/screen"???
2. ????android:layout_width="fill_parent"??android:layout_height=?"fill_parent"???
3. ????android:orientation="vertical"?>??
4. ????<TextView?android:id="@+id/left_text"???
5. ????????android:layout_width="wrap_content"???
6. ????????android:layout_height="wrap_content"???
7. ????????android:layout_alignParentLeft="true"???
8. ????????android:text="@string/custom_title_left"??/>??
9. </RelativeLayout>??

Java代码?

2. ????android:layout_width="fill_parent"?android:layout_height="fill_parent"??
3. ????android:orientation="vertical">??
