Android实现沉浸式（透明）状态栏(Eclipse版)

沉浸式状态栏的实现是要以Activity中的布局的颜色来实现的。所以要在Activity的顶部添加一个沉浸式状态栏需要颜色的控件。不同的沉浸色可以通过设置view的颜色的变化来设置。

贴代码：

包 ImmersedStatusbarUtils类

import android.app.Activity;
import android.content.Context;
import android.os.Build;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;

public class ImmersedStatusbarUtils {

public static void initAfterSetContentView(Activity activity,
View titleViewGroup) {
if (activity == null)
return;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window window = activity.getWindow();
//透明状态栏
window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
}
if (titleViewGroup == null)
return;
// 设置头部控件ViewGroup的PaddingTop,防止界面与状态栏重叠
int statusBarHeight = getStatusBarHeight(activity);
titleViewGroup.setPadding(0, statusBarHeight, 0, 0);

}

private static int getStatusBarHeight(Context context) {
int result = 0;
int resourceId = context.getResources().getIdentifier(
"status_bar_height", "dimen", "android");
if (resourceId > 0) {
result = context.getResources().getDimensionPixelSize(resourceId);
}
return result;
}
}

包 MainActivity类

import com.example.statuse.utilss.ImmersedStatusbarUtils;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.Window;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
View topView = findViewById(R.id.lin);
ImmersedStatusbarUtils.initAfterSetContentView(this, topView);
}

}

布局文件 activity_main.xml

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.example.statuse.MainActivity" >

android:id="@+id/lin"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ff123654" >

android:id="@+id/title"
android:layout_width="match_parent"
android:layout_height="45.0dp"
android:background="#ff123654"
android:gravity="center"
android:text="我是头部控件"
android:textColor="#ffffffff" />
