Android自定义状态栏颜色与APP风格保持一致的实现方法

<p>我们知道iOS上的应用，状态栏的颜色总能与应用标题栏颜色保持一致，用户体验很不错，那安卓是否可以呢？若是在安卓4.4之前，答案是否定的，但在4.4之后，谷歌允许开发者自定义状态栏背景颜色啦，这是个不错的体验！若你手机上安装有最新版的qq，并且你的安卓SDK版本是4.4及以上，你可以看下它的效果：</p>

<p><span style="color: #ff0000"><strong>实现此功能有两种方法：</strong></span></p>
<p><strong>1.在xml中设置主题或自定义style；</strong></p>
<div class="blockcode">
<pre class="brush:java;">
Theme.Holo.Light.NoActionBar.TranslucentDecor
Theme.Holo.NoActionBar.TranslucentDecor
<style name="AppTheme" parent="AppBaseTheme">

<item name="android:windowTranslucentStatus">true</item>

<item name="android:windowTranslucentNavigation">true</item>
</style></pre>
</div>
<p>鉴于市面上各种手机的SDK的各种版本，不建议采用这种方法；</p>
<p><strong>2.在代码中控制；</strong></p>
<p>可以首先创建一个BaseActivity，在onCreate方法中进行处理：</p>
<div class="blockcode">
<pre class="brush:java;">
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
setTranslucentStatus(true);
SystemBarTintManager tintManager = new SystemBarTintManager(this);
tintManager.setStatusBarTintEnabled(true);
tintManager.setStatusBarTintResource(R.color.top_bg_color);//通知栏所需颜色
}
setContentView(R.layout.main_activity);
}
@TargetApi(19)
private void setTranslucentStatus(boolean on) {
Window win = getWindow();
WindowManager.LayoutParams winParams = win.getAttributes();
final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
if (on) {
winParams.flags |= bits;
} else {
winParams.flags &= ~bits;
}
win.setAttributes(winParams);
}</pre>
</div>
<p>需注意的是， tintManager.setStatusBarTintResource(R.color.top_bg_color);这一步的颜色值（即把你的状态栏颜色与你的标题栏颜色保持一致）要写在color.xml中去，如果用Color.praseColor则会报错。</p>
