2 使用
在BaseActivity中使用
package com.yds.jianshu.base.mvp;
import android.content.Context;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.view.Window;
import com.yds.jianshu.utils.statusbar.StatusBarUtil;
/**
* Created by yds
* on 2019/8/3.
*/
public abstract class BaseActivity<P extends IBasePresenter> extends AppCompatActivity implements IBaseView{
......
@Override
protected void onCreate(@Nullable Bundle saveInstanceState){
super.onCreate(saveInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
initLayout(saveInstanceState);
mPresenter = setPresenter();
if(mPresenter!=null){
mPresenter.attach(this);
}
initViews();
initEvents();
//沉浸式代码配置
//当FitsSystemWindows设置 true 时，会在屏幕最上方预留出状态栏高度的 padding
StatusBarUtil.setRootViewFitsSystemWindows(this,true);
//设置状态栏透明
StatusBarUtil.setTranslucentStatus(this);
//一般的手机的状态栏文字和图标都是白色的, 可如果你的应用也是纯白色的, 或导致状态栏文字看不清
//所以如果你是这种情况,请使用以下代码, 设置状态使用深色文字图标风格, 否则你可以选择性注释掉这个if内容
if (!StatusBarUtil.setStatusBarDarkTheme(this,true)){
//如果不支持设置深色风格 为了兼容总不能让状态栏白白的看不清, 于是设置一个状态栏颜色为半透明,
//这样半透明+白=灰, 状态栏的文字能看得清
StatusBarUtil.setStatusBarColor(this,0x55000000);
}
}
.....
在MainActivity中使用
public class MainActivity extends BaseActivity<MainContract.IMainPresenter> implements MainContract.IMainView {
......
@Override
protected void onCreate(@Nullable Bundle saveInstanceState) {
super.onCreate(saveInstanceState);
//用来设置整体下移，状态栏沉浸
StatusBarUtil.setRootViewFitsSystemWindows(this,false);
}
......
}
在styles.xml文件中
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<!--设置无标题-->
<item name="windowNoTitle">true</item>
<item name="android:windowActionBar">false</item>
</style>
注意，在使用这个步骤过程之前，请把之前设置的代码注释一下
1、把布局带有android:fitsSystemWindows注释掉
2、style文件中凡是在style.xml中 有关 windowTranslucentNavigation、windowTranslucentStatus、statusBarColor 也注释掉不要出现
