[置顶] android 4.0解锁UI修改1

Android 4.0 解锁界面有多种,可以在Settings中“安全”,“屏幕设定”中设置,默认滑动当触屏时左边显示拍照功能图标,右边显示解锁图标。其它几种“无”,“图案”,“密码”原理一样的可以去顺藤摸瓜。我对4.0还是出认识,有些地方不正确喜欢高人指正。后面几种布局文件修改后续推出。

锁屏java类frameworks/base/policy/src/com/android/internal/policy/impl/LockScreen.java中的构造函数可以看到一段代码

finalLayoutInflater inflater = LayoutInflater.from(context);

   if (DBG) Log.v(TAG, "Creation orientation = " +mCreationOrientation);

   if (mCreationOrientation != Configuration.ORIENTATION_LANDSCAPE) {

        inflater.inflate(R.layout.keyguard_screen_tab_unlock, this, true);

    }else {

        inflater.inflate(R.layout.keyguard_screen_tab_unlock_land, this, true);

}

是当前页面横竖屏布局文件。


滑动布局文件在frameworks/base/core/res/res/layout/keyguard_screen_tab_unlock_land.xml(keyguard_screen_tab_unlock.xml)两个布局是针对横竖屏的。在这个布局文件中找到

<!-- Column 2 -->

   <com.android.internal.widget.multiwaveview.MultiWaveView

       android:id="@+id/unlock_widget"

       android:layout_width="200dip"

       android:layout_height="match_parent"

       android:layout_rowSpan="7"

 

       android:targetDrawables="@array/lockscreen_targets_with_camera"

       android:targetDescriptions="@array/lockscreen_target_descriptions_with_camera"

       android:directionDescriptions="@array/lockscreen_direction_descriptions"

       android:handleDrawable="@drawable/ic_lockscreen_handle"

       android:waveDrawable="@drawable/ic_lockscreen_outerring"

       android:outerRadius="@dimen/multiwaveview_target_placement_radius"

       android:snapMargin="@dimen/multiwaveview_snap_margin"

       android:hitRadius="@dimen/multiwaveview_hit_radius"

       android:topChevronDrawable="@drawable/ic_lockscreen_chevron_up"

       android:feedbackCount="3"

       android:vibrationDuration="20"

       android:horizontalOffset="0dip"

       android:verticalOffset="0dip"

       />

该布局在frameworks/base/core/java/com/android/internal/widget/multiwaveview下改文件下主要是做了一些图片动画,图片状态还有就是事件操作。

 

android:targetDrawables="@array/lockscreen_targets_with_camera"可以查看arrays.xml文件

frameworks/base/core/res/res/values/arrays.xml根据

<array name="lockscreen_targets_with_camera">

       <item>@drawable/ic_lockscreen_unlock</item>

       <item>@null</item>

       <item>@drawable/ic_lockscreen_camera</item>

       <item>@null</item>

</array>找到drawable文件夹下的配置文件ic_lockscreen_unlock,ic_lockscreen_camera两个配置文件就可以找到相应的UI图片,对其进行图片的修改就很容易了。
