Android 系统状态栏一体化实现

自上周更新了QQ手机客户端，对于新版本的QQ，系统状态栏也有蓝色色调，看起来有种清爽感觉。于是想自已也实现这种效果，随查阅资料，自已调试实现这种效果。Android 系统4.4以上都可以具备这种效果。所以测试时候，需要测试手机Android系统版本为4.4以上，才会出现这个效果。附上本文源码以及效果图。

一、效果图

二、看MainActivity实现类

package com.example.systemstatusdemo;import android.os.Build;import android.os.Bundle;import android.annotation.TargetApi;import android.app.Activity;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.view.Window;import android.view.WindowManager;import android.widget.TextView;public class MainActivity extends Activity implements OnClickListener{@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);setTranslucentStatus();InitView();}private void InitView() {//标题栏控件TextView mTitle = (TextView) findViewById(R.id.ivTitleName);mTitle.setText("默默笙箫");TextView mTitleLeftBtn = (TextView) findViewById(R.id.ivTitleBtnLeft);mTitleLeftBtn.setVisibility(View.VISIBLE);mTitleLeftBtn.setOnClickListener(this);}//设置系统状态栏@TargetApi(Build.VERSION_CODES.HONEYCOMB)private void setTranslucentStatus() {//判断版本是4.4以上if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){Window win = getWindow();WindowManager.LayoutParams winParams = win.getAttributes();final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;winParams.flags |= bits;win.setAttributes(winParams);SystemStatusManager tintManager = new SystemStatusManager(this);//打开系统状态栏控制tintManager.setStatusBarTintEnabled(true);tintManager.setStatusBarTintResource(R.drawable.chat_title_bg_repeat);//设置背景View layoutAll = findViewById(R.id.layoutAll);//设置系统栏需要的内偏移layoutAll.setPadding(0, ScreenUtils.getStatusHeight(this), 0, 0);}}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}@Overridepublic void onClick(View v) {switch (v.getId()) {case R.id.ivTitleBtnLeft:finish();break;default:break;}}}

四、屏幕相关的辅助类ScreenUtils

package com.ycf.systemstatus;import android.app.Activity;import android.content.Context;import android.graphics.Bitmap;import android.graphics.Rect;import android.util.DisplayMetrics;import android.view.View;import android.view.WindowManager;/** * 获得屏幕相关的辅助类 */public class ScreenUtils{private ScreenUtils(){throw new UnsupportedOperationException("cannot be instantiated");}/** * 获得屏幕高度 *  * @param context * @return */public static int getScreenWidth(Context context){WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);DisplayMetrics outMetrics = new DisplayMetrics();wm.getDefaultDisplay().getMetrics(outMetrics);return outMetrics.widthPixels;}/** * 获得屏幕宽度 *  * @param context * @return */public static int getScreenHeight(Context context){WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);DisplayMetrics outMetrics = new DisplayMetrics();wm.getDefaultDisplay().getMetrics(outMetrics);return outMetrics.heightPixels;}/** * 获得状态栏的高度 *  * @param context * @return */public static int getStatusHeight(Context context){int statusHeight = -1;try{Class<?> clazz = Class.forName("com.android.internal.R$dimen");Object object = clazz.newInstance();int height = Integer.parseInt(clazz.getField("status_bar_height").get(object).toString());statusHeight = context.getResources().getDimensionPixelSize(height);} catch (Exception e){e.printStackTrace();}return statusHeight;}/** * 获取当前屏幕截图，包含状态栏 *  * @param activity * @return */public static Bitmap snapShotWithStatusBar(Activity activity){View view = activity.getWindow().getDecorView();view.setDrawingCacheEnabled(true);view.buildDrawingCache();Bitmap bmp = view.getDrawingCache();int width = getScreenWidth(activity);int height = getScreenHeight(activity);Bitmap bp = null;bp = Bitmap.createBitmap(bmp, 0, 0, width, height);view.destroyDrawingCache();return bp;}/** * 获取当前屏幕截图，不包含状态栏 *  * @param activity * @return */public static Bitmap snapShotWithoutStatusBar(Activity activity){View view = activity.getWindow().getDecorView();view.setDrawingCacheEnabled(true);view.buildDrawingCache();Bitmap bmp = view.getDrawingCache();Rect frame = new Rect();activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);int statusBarHeight = frame.top;int width = getScreenWidth(activity);int height = getScreenHeight(activity);Bitmap bp = null;bp = Bitmap.createBitmap(bmp, 0, statusBarHeight, width, height- statusBarHeight);view.destroyDrawingCache();return bp;}}

需要注意的是：1、所以测试时候，需要测试手机Android系统版本为4.4以上，才具有这种效果。

                          2、android:theme="@android:style/Theme.Translucent.NoTitleBar"在项目AndroidManifest.xml配置一下。
