状态栏(一)
状态栏(二)
经过前两篇的介绍我们对如何修改状态栏的效果有了大致的了解,本篇介绍一种使用更加简单的方式,可以先拉到最后查看效果图。
设置主题效果
注意: 要设置fitsSystemWindows为true
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:fitsSystemWindows">true</item>
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>

参考SystemBarTint对状态栏的改变方式,添加下面这个类方法,用来设置 API 19 以上的状态栏效果
我们的界面绘制时在DecorView中的,这个类的核心思想就是:
1.获取DecorView
2.绘制状态栏高度的View
3.将view添加到DecorView中
所以我们对状态栏的操作,其实就是对view的操作。在这个类中默认view不显示,改变状态栏的效果时,要调用
setStatusBarTintEnabled(true)
1
注意:使用这个方法的前提是 状态栏是透明的,因为进行了相关的判断(可以自行修改)
public class SystemBarTintManager {
public static final int DEFAULT_TINT_COLOR = 0x99000000;
private boolean mStatusBarAvailable;
private boolean mStatusBarTintEnabled;
private View mStatusBarTintView;
@TargetApi(19)
public SystemBarTintManager(Activity activity) {
Window win = activity.getWindow();
//获取DecorView
ViewGroup decorViewGroup = (ViewGroup) win.getDecorView();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
// 检查主题中是否有透明的状态栏
int[] attrs = {android.R.attr.windowTranslucentStatus};
TypedArray a = activity.obtainStyledAttributes(attrs);
try {
mStatusBarAvailable = a.getBoolean(0, false);
} finally {
a.recycle();
}
WindowManager.LayoutParams winParams = win.getAttributes();
int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;//状态栏透明
if ((winParams.flags & bits) != 0) {
mStatusBarAvailable = true;
}
}
if (mStatusBarAvailable) {
setupStatusBarView(activity, decorViewGroup);
}
}
/**
* 初始化状态栏
*
* @param context
* @param decorViewGroup
*/
private void setupStatusBarView(Activity context, ViewGroup decorViewGroup) {
mStatusBarTintView = new View(context);
//设置高度为Statusbar的高度
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, getStatusBarHeight(context));
params.gravity = Gravity.TOP;
mStatusBarTintView.setLayoutParams(params);
mStatusBarTintView.setBackgroundColor(DEFAULT_TINT_COLOR);
//默认不显示
mStatusBarTintView.setVisibility(View.GONE);
//decorView添加状态栏高度的View
decorViewGroup.addView(mStatusBarTintView);
}
/**
* 获取状态栏高度
*
* @param activity
* @return
*/
private int getStatusBarHeight(Activity activity) {
int statusBarHeight = 0;
int resourceId = activity.getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
statusBarHeight = activity.getResources().getDimensionPixelSize(resourceId);
}
return statusBarHeight;
}
/**

*/
public void setStatusBarTintEnabled(boolean enabled) {
mStatusBarTintEnabled = enabled;
if (mStatusBarAvailable) {
mStatusBarTintView.setVisibility(enabled ? View.VISIBLE : View.GONE);
}
}
/**

*/
public void setStatusBarTintColor(int color) {
if (mStatusBarAvailable) {
mStatusBarTintView.setBackgroundColor(color);
}
}

工具类代码
在这段代码中当我们的API 为4.4.+ 但是小于 5.0时使用上述的类
/**
* 修改状态栏颜色,支持4.4以上版本
* @param colorId 颜色
*/
public static void setStatusBarColor(Activity activity, int colorId) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Window window = activity.getWindow();
window.setStatusBarColor(colorId);
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
//使用SystemBarTintManager,需要先将状态栏设置为透明
setTranslucentStatus(activity);
SystemBarTintManager systemBarTintManager = new SystemBarTintManager(activity);
systemBarTintManager.setStatusBarTintEnabled(true);//显示状态栏
systemBarTintManager.setStatusBarTintColor(colorId);//设置状态栏颜色
}
}

使用方式
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
StatusBarUtil.setImmersiveStatusBar(this,true);
}
}

第二个参数是设置是否为黑色字体。
我们还可以调用下面代码设置状态栏颜色。
StatusBarUtil.setStatusBarColor(Activity activity, int colorId)

效果
使用时只需要一行代码就可以改变状态栏的字体颜色,是不是很简单呢。
请在github上下载完整的内容,工具类在statusbarutil中。
