android中沉浸式状态栏,Android 中沉浸式状态栏实现(一)

Android 中沉浸式状态栏实现方式如下

计算状态栏高度及调用沉浸式状态栏的相关API方法

package com.example.status;

import android.annotation.TargetApi;

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 {

/**

* 在{@link Activity#setContentView}之后调用

*

* @param activity

* 要实现的沉浸式状态栏的Activity

* @param titleViewGroup

* 头部控件的ViewGroup,若为null,整个界面将和状态栏重叠

*/

@TargetApi(Build.VERSION_CODES.KITKAT)

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();

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);

}

/**

* 获取状态栏高度

*

* @param context

* @return

*/

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;

}

}

调用实例，使用步骤一编写的相关方法。

package com.example.status;

import android.app.Activity;

import android.os.Bundle;

import android.view.Menu;

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);

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.main, menu);

return true;

}

}

对应的布局文件

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical" >

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" />
