miui v7 android4.4.4效果                                                          android 6.0 效果


      


基类Activity

package com.example.sss;

import android.graphics.Color;
import android.os.Build;
import android.os.Bundle;
import android.support.annotation.LayoutRes;
import android.support.v4.app.FragmentActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.Window;
import android.view.WindowManager;
import android.widget.FrameLayout;

public class SupportActivity extends FragmentActivity  {

@Override
protected void onCreate(Bundle arg0) {
super.onCreate(arg0);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window window = getWindow();
// Translucent status bar
window.setFlags(
WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,
WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

setStatusBarColor(0);
}
}
/**
* 设置状态栏颜色
* @param color   0 黑色
*/
protected  void setStatusBarColor(int color){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
if (color==0){
getWindow().getDecorView().setBackgroundColor(Color.BLACK);
}else {
getWindow().getDecorView().setBackgroundColor(getResources().getColor(color));
}

}
}

@Override
public void setContentView(@LayoutRes int layoutResID) {

FrameLayout container=new FrameLayout(this);
//在用户布局外面嵌套一个FrameLayout，防止用户布局中根控件的margin失效
LayoutInflater.from(this).inflate(layoutResID,container,true);
setContentView(container);

}

@Override
public void setContentView(View view) {
super.setContentView(view);
adjustContentMargin(view);
}

private void adjustContentMargin(View view){
ViewGroup.LayoutParams param=view.getLayoutParams();

ViewGroup.MarginLayoutParams margParam;
if (param instanceof ViewGroup.MarginLayoutParams){

margParam=(ViewGroup.MarginLayoutParams) param;
margParam.setMargins(margParam.leftMargin,margParam.topMargin+getStatusBarHeight(),margParam.rightMargin,margParam.bottomMargin);
}else{

margParam=new ViewGroup.MarginLayoutParams(param);
margParam.setMargins(0,getStatusBarHeight(),0,0);
}
view.setLayoutParams(margParam);
}
protected int getStatusBarHeight() {
int result = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
result = getResources().getDimensionPixelSize(resourceId);
}
return result;
}
}

使用

package com.example.sss;

import android.annotation.SuppressLint;
import android.os.Bundle;
public class MainActivity extends SupportActivity {

@SuppressLint("ResourceAsColor")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

setStatusBarColor(R.color.colorPrimary);
}

}

布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity"
android:background="#fff"

>

<RelativeLayout

android:layout_width="match_parent"
android:layout_height="48dp"
android:background="@color/colorPrimary"
>

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="标题"
android:textSize="20sp"
android:textColor="#fff"
android:layout_centerInParent="true"/>

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="返回"
android:layout_centerVertical="true"
android:textColor="#fff"
/>

</RelativeLayout>

<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:gravity="center"

android:text="hello" />
</LinearLayout>

颜色资源

<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="colorPrimary">#18b4ed</color>
<color name="colorPrimaryDark">#18b4ed</color>
<color name="colorAccent">#FF4081</color>

<color name="colorRed">#ff003b</color>
</resources>

注意，要设置没有标题栏，可以在activity中设置，也可以在xml中配置：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.sss"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="21" />

<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

</manifest>

values文件夹中styles.xml

<resources>

<!--
Base application theme, dependent on API level. This theme is replaced
by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
-->
<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
<!--
Theme customizations available in newer API levels can go in
res/values-vXX/styles.xml, while customizations related to
backward-compatibility can go here.
-->
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

</resources>

上面的方案中键盘弹出时可能导致布局上移，但从状态栏依旧能看到布局，采用下面方案可解决

package com.example.imageloader;

import android.graphics.Color;
import android.os.Build;
import android.os.Bundle;
import android.support.annotation.LayoutRes;
import android.support.v4.app.FragmentActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.Window;
import android.view.WindowManager;
import android.widget.FrameLayout;

public class SupportActivity extends FragmentActivity {

private View statusBar;
@Override
protected void onCreate(Bundle arg0) {
super.onCreate(arg0);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window window = getWindow();
// Translucent status bar
window.setFlags(
WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,
WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

statusBar=new View(this);
ViewGroup.LayoutParams param=new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,getStatusBarHeight());
statusBar.setLayoutParams(param);
setStatusBarColor(0);
}
}
/**
* 设置状态栏颜色
* @param color 0 黑色
*/
protected void setStatusBarColor(int color){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
if (color==0){
statusBar.setBackgroundColor(Color.BLACK);
}else {
statusBar.setBackgroundColor(getResources().getColor(color));
}

}
}

@Override
public void setContentView(@LayoutRes int layoutResID) {

FrameLayout container=new FrameLayout(this);
//在用户布局外面嵌套一个FrameLayout，防止用户布局中根控件的margin失效
LayoutInflater.from(this).inflate(layoutResID,container,true);
setContentView(container);

}

@Override
public void setContentView(View view) {
super.setContentView(view);
adjustContentMargin(view);
((ViewGroup)getWindow().getDecorView()).addView(statusBar);
}

private void adjustContentMargin(View view){
ViewGroup.LayoutParams param=view.getLayoutParams();

ViewGroup.MarginLayoutParams margParam;
if (param instanceof ViewGroup.MarginLayoutParams){

margParam=(ViewGroup.MarginLayoutParams) param;
margParam.setMargins(margParam.leftMargin,margParam.topMargin+getStatusBarHeight(),margParam.rightMargin,margParam.bottomMargin);
}else{

margParam=new ViewGroup.MarginLayoutParams(param);
margParam.setMargins(0,getStatusBarHeight(),0,0);
}
view.setLayoutParams(margParam);
}
protected int getStatusBarHeight() {
int result = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
result = getResources().getDimensionPixelSize(resourceId);
}
return result;
}
}
