要用时，StatusBarUtils .setBar(this); 就行了。
比如：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//调用一下就行了。
StatusBarUtils .setBar(this);
setContentView(R.layout.activity_home);
.....................................
然后坑爹就出现了，状态栏和我们的布局有重合的了，
有的说在根布局下添加android:fitsSystemWindows="true"属性，
也用过
// 在setContentView之前执行
public void setStatusBar() {
/*
为统一标题栏与状态栏的颜色，我们需要更改状态栏的颜色，而状态栏文字颜色是在android 6.0之后才可以进行更改
所以统一在6.0之后进行文字状态栏的更改
*/
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (isUseFullScreenMode()) {
StatusBarUtils.transparencyBar(this);
} else {
StatusBarUtils.setStatusBarColor(this, setStatusBarColor());
}
if (isUserLightMode()) {
StatusBarUtils.setLightStatusBar(this, true);
}
}
}
// 是否设置成透明状态栏，即就是全屏模式
protected boolean isUseFullScreenMode() {
return false;
}
protected int setStatusBarColor() {
return R.color.transparent;
}
// 是否改变状态栏文字颜色为黑色，默认为黑色
protected boolean isUserLightMode() {
return true;
}
然后在
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStatusBar();
setContentView(R.layout.activity_information);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
View content = ((ViewGroup) findViewById(android.R.id.content)).getChildAt(0);
if (content != null && !isUseFullScreenMode()) {
content.setFitsSystemWindows(true);
}
}
感觉行，在我这里，实际好像没有多大用处，先记录在这里，万一以后做参考。
实际上，在styles.xml文件中。在当前使用的风格里添加
<item name="android:fitsSystemWindows">true</item>//设置应用布局时是否考虑系统窗口布局即可发现属性都是同一个属性，只是位置不同。
<item name="android:windowTranslucentStatus" tools:targetApi="kitkat">true</item> //透明的状态栏
<item name="android:windowTranslucentNavigation" tools:targetApi="kitkat">true</item>//透明的导航图
