Android 开发之自定义标题栏、状态栏
在我们开发的 APP 中，有时会对状态栏修改其颜色，会对标题栏进行统一，下面我会带来自定义标题栏，和快速的修改状态栏颜色；先上效果图：

状态栏颜色修改
1，StatusBarCompat.java
package com.gyq.some_dialog;
import android.annotation.TargetApi;
import android.app.Activity;
import android.content.Context;
import android.graphics.Color;
import android.os.Build;
import android.view.View;
import android.view.ViewGroup;
/**

*/
public class StatusBarCompat {
private static final int INVALID_VAL = -1;
private static final int COLOR_DEFAULT = Color.parseColor("#20000000");
@TargetApi(Build.VERSION_CODES.LOLLIPOP)
public static void compat(Activity activity, int statusColor)
{
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
{
if (statusColor != INVALID_VAL)
{
activity.getWindow().setStatusBarColor(statusColor);
}
return;
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP)
{
int color = COLOR_DEFAULT;
ViewGroup contentView = (ViewGroup) activity.findViewById(android.R.id.content);
if (statusColor != INVALID_VAL)
{
color = statusColor;
}
View statusBarView = contentView.getChildAt(0);
//改变颜色时避免重复添加statusBarView
if (statusBarView != null && statusBarView.getMeasuredHeight() == getStatusBarHeight(activity))
{
statusBarView.setBackgroundColor(color);
return;
}
statusBarView = new View(activity);
ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
getStatusBarHeight(activity));
statusBarView.setBackgroundColor(color);
contentView.addView(statusBarView, lp);
}
}
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;
}
}
2，在对应的 activity处添加如下代码即可
//状态栏颜色，填入参数二
StatusBarCompat.compat(this, getResources().getColor(R.color.status_bar_color));
//StatusBarCompat.compat(this);自定义标题栏
