ActionBar配合简单自定义Pop使用

最近公司项目用到了actionBar然后因需求又要配合自定义pop才能实现，最后实现了，写下来记录下，方便以后查看。
那先来看看实现效果吧

项目结构也是很简单的，就是自己从项目中抽取了一个小demo.

下面直接上代码
MainActivity代码

package wlj.com.actionbar;


import android.app.Activity;
import android.graphics.drawable.ColorDrawable;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.PopupWindow;
import android.widget.TextView;
import android.widget.Toast;

/**
 * @author wlj
 * @date 2016/7/30
 */
public class MainActivity extends Activity implements View.OnClickListener {

private android.app.ActionBar actionBar;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initBar();
    }

/**
 * 初始化action bar
 */
private void initBar() {
//得到Actionbar
        actionBar = getActionBar();
//显示actionbar的返回箭头
        actionBar.setDisplayHomeAsUpEnabled(true);
//不显示应用图标
        actionBar.setDisplayShowHomeEnabled(false);
        actionBar.setDisplayUseLogoEnabled(true);
//设置标题名字
        actionBar.setTitle("ActionBar");
//设置Actionbar的背景
        actionBar.setBackgroundDrawable(getResources().getDrawable(R.drawable.green_bar));
    }

/**
 * 添加bar 按钮
 *
 * @param menu
 * @return
 */
@Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.search_menu, menu);
return true;
    }

/**
 * 根据选择的id做出对应的判断
 *
 * @param item actionbar id
 * @return
 */
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int itemId = item.getItemId();
switch (itemId) {
//系统默认的左上角
case android.R.id.home:
                onBackPressed();
break;
case R.id.show_data1:
//自定义popupwidow
                PopuWindow();
return true;
        }
return super.onOptionsItemSelected(item);
    }

/**
 * 自定义pop
 */
public void PopuWindow() {
        LayoutInflater inflater = (LayoutInflater) MainActivity.this.getSystemService(MainActivity.LAYOUT_INFLATER_SERVICE);
        View inflate = inflater.inflate(R.layout.pop, null);
        TextView search1 = (TextView) inflate.findViewById(R.id.search_tv1);
        TextView search2 = (TextView) inflate.findViewById(R.id.search_tv2);
        TextView search3 = (TextView) inflate.findViewById(R.id.search_tv3);
        TextView search4 = (TextView) inflate.findViewById(R.id.search_tv4);
        TextView search5 = (TextView) inflate.findViewById(R.id.search_tv5);
        search1.setOnClickListener(this);
        search2.setOnClickListener(this);
        search3.setOnClickListener(this);
        search4.setOnClickListener(this);
        search5.setOnClickListener(this);
        PopupWindow popupWindow = new PopupWindow(this);
int height = MainActivity.this.getWindowManager().getDefaultDisplay().getHeight();
int width = MainActivity.this.getWindowManager().getDefaultDisplay().getWidth();
// 设置SelectPicPopupWindow的View
        popupWindow.setContentView(inflate);
// 设置SelectPicPopupWindow的View
        popupWindow.setWidth(width / 3 + 50);
// 设置SelectPicPopupWindow弹出窗体的高
        popupWindow.setHeight(LinearLayout.LayoutParams.WRAP_CONTENT);
// 设置SelectPicPopupWindow弹出窗体可点击
        popupWindow.setFocusable(true);
        popupWindow.setOutsideTouchable(true);
// 刷新状态
        popupWindow.update();
// 实例化一个ColorDrawable颜色为半透明
        ColorDrawable dw = new ColorDrawable(0000000000);
// 点back键和其他地方使其消失,设置了这个才能触发OnDismisslistener ，设置其他控件变化等操作
        popupWindow.setBackgroundDrawable(dw);
        View viewById = findViewById(R.id.show_data1);
        popupWindow.showAsDropDown(viewById, viewById.getLayoutParams().width / 2, 0);
    }

/**
 * 自定义pop点击事件
 *
 * @param v 根据id
 */
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.search_tv1:
// 选项1
                Toast.makeText(this, "选项1", Toast.LENGTH_SHORT).show();
break;
case R.id.search_tv2:
// 选项2
                Toast.makeText(this, "选项2", Toast.LENGTH_SHORT).show();
break;
case R.id.search_tv3:
// 选项3
                Toast.makeText(this, "选项3", Toast.LENGTH_SHORT).show();
break;
case R.id.search_tv4:
// 选项4
                Toast.makeText(this, "选项4", Toast.LENGTH_SHORT).show();
break;
case R.id.search_tv5:
// 选项5
                Toast.makeText(this, "选项5", Toast.LENGTH_SHORT).show();
break;
        }
    }
}

activity_main代码

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="wlj.com.actionbar.MainActivity">

<TextView
 android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!" />
</RelativeLayout>

自定义pop样式代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/ll_search"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/green_bar"
android:gravity="center_horizontal"
android:orientation="vertical">

<TextView
 android:id="@+id/search_tv1"
android:layout_width="match_parent"
android:layout_height="50dp"
android:gravity="center"
android:padding="8dp"
android:text="选项1"
android:textColor="#ffffff"
android:textSize="18sp" />

<View
 android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#22000000" />

<TextView
 android:id="@+id/search_tv2"
android:layout_width="match_parent"
android:layout_height="50dp"
android:gravity="center"
android:padding="8dp"
android:text="选项2"
android:textColor="#ffffff"
android:textSize="18sp"

 />

<View
 android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#22000000" />

<TextView
 android:id="@+id/search_tv3"
android:layout_width="match_parent"
android:layout_height="50dp"
android:gravity="center"
android:padding="8dp"
android:text="选项3"
android:textColor="#ffffff"
android:textSize="18sp"

 />

<View
 android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#22000000" />

<TextView
 android:id="@+id/search_tv4"
android:layout_width="match_parent"
android:layout_height="50dp"
android:gravity="center"
android:padding="8dp"
android:text="选项4"
android:textColor="#ffffff"
android:textSize="18sp"

 />

<View
 android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#22000000" />

<TextView
 android:id="@+id/search_tv5"
android:layout_width="match_parent"
android:layout_height="50dp"
android:gravity="center"
android:padding="8dp"
android:text="选项5"
android:textColor="#ffffff"
android:textSize="18sp"

 />
</LinearLayout>

menu中代码

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
 android:id="@+id/show_data1"
android:icon="@drawable/abc_ic_menu_moreoverflow_normal_holo_dark"
android:showAsAction="always" />
</menu>

代码是就以上这些，不过有以下一些地方需要注意的
MainActivity继承自Activity
AndroidManifest中给MainActivity设置主题
android:theme=”@android:style/Theme.Holo.Light.DarkActionBar”
好了，最后我们再完整的看一遍演示效果
