android framework SystemUI 修改NavigationBar靠右边

来源：互联网发布：淘宝男装店铺简介编辑：程序博客网时间：2024/06/01 12:05

1、alps\frameworks\base\policy\src\com\android\internal\policy\impl\PhoneWindowManager.java找到这个文件然后在 public void setInitialDisplaySize(Display display, int width, int height, int density) {}方法中找到 mNavigationBarCanMove = true;//shortSizeDp < 600; //syc 20141112 mNavigationBarCanMove这个变量就代表NavigationBar是否能移动安卓源码默认提供了修改到右边的方法。

2、就是需要修改SystemUI中的布局了别着急跟着我继续找 alps\frameworks\base\packages\SystemUI\res\layout\navigation_bar.xml 我把布局中我修改的代码拿出来

<com.android.systemui.statusbar.phone.NavigationBarView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:systemui="http://schemas.android.com/apk/res/com.android.systemui"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:background="@drawable/system_bar_background"
>

<FrameLayout android:id="@+id/rot0"
android:layout_height="match_parent"
android:layout_width="match_parent"
>

<LinearLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="vertical"
android:clipChildren="false"
android:clipToPadding="false"
android:id="@+id/nav_buttons"
android:animateLayoutChanges="true"
>

<View
android:layout_width="match_parent"
android:layout_height="8dp"

android:layout_marginLeft="2dp"
android:visibility="invisible"
/>
<Space
android:layout_width="match_parent"
android:layout_height="28dp"

/>

<com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/volume_up"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/my_volume_up"
systemui:keyCode="24"

systemui:glowBackground="@drawable/ic_sysbar_highlight"
android:contentDescription="@string/accessibility_recent"
/>



<com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/volume_down"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="38dip"
android:background="@drawable/my_volume_down"
systemui:keyCode="25"

systemui:glowBackground="@drawable/ic_sysbar_highlight"

/>


<LinearLayout
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:orientation="horizontal"
android:layout_marginTop="50dip"

<ImageButton
android:id="@+id/hide_bar_btn"
android:layout_height="52dp"
android:layout_width="22dp"
android:layout_marginTop="15dip"

</ImageButton>

<ImageButton android:id="@+id/voice_apps"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dip"
android:layout_marginLeft="10dip"

android:background="@drawable/my_voice"
systemui:glowBackground="@drawable/ic_sysbar_highlight"
/>
</LinearLayout>

<com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/back"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="@drawable/my_back"
systemui:keyCode="4"
android:layout_marginTop="55dip"
systemui:glowBackground="@drawable/ic_sysbar_highlight"
android:contentDescription="@string/accessibility_back"
/>
<com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/home"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="@drawable/my_home"
systemui:keyCode="3"
systemui:keyRepeat="true"
android:layout_marginTop="50dip"
systemui:glowBackground="@drawable/ic_sysbar_highlight"
android:contentDescription="@string/accessibility_home"

<Space

android:layout_width="48dp"

android:layout_marginRight="2dp"
systemui:keyCode="82"
android:visibility="invisible"
android:contentDescription="@string/accessibility_menu"
systemui:glowBackground="@drawable/ic_sysbar_highlight"
/>
</LinearLayout>


<LinearLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="horizontal"
android:id="@+id/lights_out"
android:visibility="gone"
>
<Space
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
/>

<com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/recent_apps"
android:layout_width="match_parent" android:paddingStart="0dp" android:paddingEnd="0dp"
android:layout_height="88dp"
android:src="@drawable/ic_sysbar_recent"
systemui:glowBackground="@drawable/ic_sysbar_highlight"
android:visibility="gone"
/>
<ImageView
android:layout_width="128dp" android:paddingLeft="25dp" android:paddingRight="25dp"
android:layout_height="match_parent"
android:layout_marginLeft="40dp"
android:src="@drawable/ic_sysbar_lights_out_dot_small"
android:scaleType="center"
android:layout_weight="0"
/>
<ImageView
android:layout_width="128dp" android:paddingLeft="25dp" android:paddingRight="25dp"
android:layout_height="match_parent"
android:src="@drawable/ic_sysbar_lights_out_dot_large"
android:scaleType="center"
android:layout_weight="0"
/>
<ImageView
android:layout_width="128dp" android:paddingLeft="25dp" android:paddingRight="25dp"
android:layout_marginRight="40dp"
android:layout_height="match_parent"
android:src="@drawable/ic_sysbar_lights_out_dot_small"
android:scaleType="center"
android:layout_weight="0"
/>
<Space
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
/>
</LinearLayout>

3、其中涉及到一些图片资源的添加自己应该能看得出来然后添加图片之后还需要添加事件需要在alps\frameworks\base\packages\SystemUI\src\com\android\systemui\statusbar\phone\NavigationBarView.java 和PhoneStatusBar.java 添加代码
