先看效果图：
package com.example.administrator.myapplication;import android.app.Activity;import android.graphics.Color;import android.os.Bundle;import android.view.Menu;import android.view.MenuItem;import android.view.ViewGroup;import android.view.Window;import android.view.WindowManager;import android.widget.LinearLayout;import android.widget.TextView;import java.lang.reflect.Field;public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        //这个方法只有在安卓4.4以上才能起作用！        if (android.os.Build.VERSION.SDK_INT > 18) {            Window window = getWindow();            window.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);            window.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);            // 创建TextView            TextView textView = new TextView(this);            LinearLayout.LayoutParams lParams = new LinearLayout.LayoutParams(WindowManager.LayoutParams.MATCH_PARENT, getStatusBarHeight());            textView.setBackgroundColor(Color.parseColor("#3F9FE0"));            textView.setLayoutParams(lParams);            // 获得根视图并把TextView加进去。            ViewGroup view = (ViewGroup) getWindow().getDecorView();            view.addView(textView);        }    }    // 获取手机状态栏高度    public int getStatusBarHeight() {        Class<?> c = null;        Object obj = null;        Field field = null;        int x = 0, statusBarHeight = 0;        try {            c = Class.forName("com.android.internal.R$dimen");            obj = c.newInstance();            field = c.getField("status_bar_height");            x = Integer.parseInt(field.get(obj).toString());            statusBarHeight = getResources().getDimensionPixelSize(x);        } catch (Exception e1) {        }        return statusBarHeight;    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.menu_main, menu);        return true;    }    @Override    public boolean onOptionsItemSelected(MenuItem item) {        // Handle action bar item clicks here. The action bar will        // automatically handle clicks on the Home/Up button, so long        // as you specify a parent activity in AndroidManifest.xml.        int id = item.getItemId();        //noinspection SimplifiableIfStatement        if (id == R.id.action_settings) {            return true;        }        return super.onOptionsItemSelected(item);    }}
剩下的就是布局很简单就实现了，像推酷的那种效果！
