仿ios状态栏颜色和标题栏颜色一致的实例代码

首先创建一个工具类

import android.annotation.TargetApi;
import android.app.Activity;
import android.content.Context;
import android.os.Build;
import android.support.v4.content.ContextCompat;
import android.view.View;
import android.view.ViewGroup;

public class StatusBarCompat {
private static final int INVALID_VAL = -1;
//判断版本
@TargetApi(Build.VERSION_CODES.LOLLIPOP)
public static View compat(Activity activity, int statusColor) {
 //默认颜色
 int color = ContextCompat.getColor(activity, R.color.colorPrimaryDark);
 //若果版本大于等于21 给状态栏设置颜色
 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
  if (statusColor != INVALID_VAL) {
   color = statusColor;
  }
  activity.getWindow().setStatusBarColor(color);
  return null;
 }
 //如果版本在大于等于19小于21
 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT
   && Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
  //获取contentView
  ViewGroup contentView = (ViewGroup) activity.findViewById(android.R.id.content);
  if (statusColor != INVALID_VAL) {
   color = statusColor;
  }
  //获取contentView里的第一个view 也就是状态栏
  View statusBarView = contentView.getChildAt(0);
  if (statusBarView != null && statusBarView.getMeasuredHeight() == getStatusBarHeight(activity)) {
   statusBarView.setBackgroundColor(color);
   return statusBarView;
  }

statusBarView = new View(activity);
  ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
    getStatusBarHeight(activity));
  statusBarView.setBackgroundColor(color);
  contentView.addView(statusBarView, lp);
  return statusBarView;
 }
 return null;
}
public static void compat(Activity activity) {
 compat(activity, INVALID_VAL);
}
public 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;
}
}

然后在activity里调用方法

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v4.content.ContextCompat;
import android.os.Build;
import android.view.WindowManager;
public class MainActivity extends AppCompatActivity {
protected boolean statusBarCompat = true;
@Override
protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 if (statusBarCompat) {
  StatusBarCompat.compat(this, ContextCompat.getColor(this, R.color.colorPrimary));
  transparent19and20();
 }
}
protected void transparent19and20() {
 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT
   && Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
  getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
 }
}
}

抄的别人的 网上一大堆，作者不要来喷我，我是为了自己以后好找到使用。
