Android：沉浸式状态栏（二）集成

1. 在Activity的onCreate()方法中添加代码

//设置状态栏透明
StatusBarUtil.setTranslucentStatus(this);
//设置透明状态栏的paddingTop为false
setRootViewFitsSystemWindows(this,false);

在使用中经常会遇到图标和标题栏重叠的情况，可以使用StatusBarHeightView这个控件填充状态栏上方的位置

package com.onepilltest.util;

import android.content.Context;
import android.content.res.TypedArray;
import android.os.Build;
import android.support.annotation.Nullable;
import android.util.AttributeSet;
import android.widget.LinearLayout;

import com.onepilltest.R;

public class StatusBarHeightView extends LinearLayout {
    private int statusBarHeight;
    private int type;

    public StatusBarHeightView(Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
        init(attrs);
    }

    public StatusBarHeightView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init(attrs);
    }

    public StatusBarHeightView(Context context, @Nullable AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr);
        init(attrs);


    }

    private void init(@Nullable AttributeSet attrs) {

        int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            if(resourceId>0) {
                statusBarHeight = getResources().getDimensionPixelSize(resourceId);
            }
        }else{
            //低版本 直接设置0
            statusBarHeight = 0;
        }
        if (attrs != null) {
            TypedArray typedArray = getContext().obtainStyledAttributes(attrs, R.styleable.StatusBarHeightView);
            type = typedArray.getInt(R.styleable.StatusBarHeightView_use_type, 0);
            typedArray.recycle();
        }
        if (type == 1) {
            setPadding(getPaddingLeft(), statusBarHeight, getPaddingRight(), getPaddingBottom());
        }
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        if (type == 0) {
            setMeasuredDimension(getDefaultSize(getSuggestedMinimumWidth(), widthMeasureSpec),
                    statusBarHeight);
        } else {
            super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        }
    }
}
