Android DrawLayout + ListView 的使用(一)

想做一个APP,设计中有侧边栏这个功能,所以现在开始学习下侧边栏的实现。

在官方的UI空间中已经给出了DrawerLayout这个侧滑的菜单空间。

因为在使用DrawerLayout的时候遇到了些问题,花了一天是时间才搞定,这里来记录一下,免得到时候自己在掉坑里。

1.主布局一定要是DrawerLayout

2.侧栏拉出来时,要点击空白栏关闭侧栏的话,一定要把空白栏设置为FrameLayout

先上个效果图吧:

好了,上代码:

activity_main.xml

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <!-- 内容栏-->
    <FrameLayout
        android:id="@+id/ly_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
    <!-- 侧滑栏-->
    <ListView
        android:id="@+id/list_left_drawer"
        android:layout_width="300dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#fff000"
        android:choiceMode="singleChoice"
        android:divider="#FFFFFF"
        android:dividerHeight="1dp" />
</android.support.v4.widget.DrawerLayout>

listView里面的布局 item_list.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
    xmlns:app="http://schemas.android.com/apk/res-auto">


    <!-- 定义一个用于显示头像的ImageView -->
    <ImageView
        android:id="@+id/imgtou"
        android:layout_width="64dp"
        android:layout_height="64dp"
        android:baselineAlignBottom="true"
        android:paddingLeft="8dp" />

    <!-- 定义一个竖直方向的LinearLayout,把QQ呢称与说说的文本框设置出来 -->
    <LinearLayout
        android:id="@+id/new_line"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <TextView
            android:id="@+id/name"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:paddingLeft="8px"
            android:textColor="#1D1D1C"
            android:textSize="20sp" />

        <TextView
            android:id="@+id/says"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:paddingLeft="8px"
            android:textColor="#B4B4B9"
            android:textSize="14sp" />

        <TextView
            android:id="@+id/time"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:paddingLeft="8px"
            android:textColor="#B4B4B9"
            android:textSize="14sp" />

    </LinearLayout>

</LinearLayout>

主程序MainActivity.java

package action.sun.com.testdraw2;

import android.support.v4.app.FragmentManager;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.Toast;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class MainActivity extends AppCompatActivity implements AdapterView.OnItemClickListener{

    private String[] names = new String[]{"Tom", "Jack", "Json"};
    private String[] says = new String[]{"111111,2222222", "33333333~", "444444444~"};
    private String[] times = new String[]{"1天前", "3天前~", "2天前~"};
    private int[] imgIds = new int[]{R.mipmap.ic_launcher, R.mipmap.ic_launcher, R.mipmap.ic_launcher};
    private DrawerLayout drawer_layout;

    private  ListView listView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Log.d("1", "onCreate: xxxxxxxxxxxxxxx");
        drawer_layout = (DrawerLayout) findViewById(R.id.drawer_layout);

        List<Map<String, Object>> listitem = new ArrayList<Map<String, Object>>();
        for (int i = 0; i < names.length; i++) {
            Map<String, Object> showitem = new HashMap<String, Object>();
            showitem.put("touxiang", imgIds[i]);
            showitem.put("name", names[i]);
            showitem.put("says", says[i]);
            showitem.put("time", times[i]);
            listitem.add(showitem);
        }

        //创建一个simpleAdapter
        SimpleAdapter myAdapter = new SimpleAdapter(getApplicationContext(), listitem,
                R.layout.item_list, new String[]{"touxiang", "name", "says","time"},
                new int[]{R.id.imgtou, R.id.name, R.id.says, R.id.time});
        //ListView 容器
        listView = (ListView) findViewById(R.id.list_left_drawer);
        listView.setAdapter(myAdapter);
        listView.setOnItemClickListener(this);

    }

    //点击Item 显示在帧页面选择的Item值
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Toast.makeText(MainActivity.this, "提示的内容", Toast.LENGTH_LONG).show();
        //关闭 侧边栏
        drawer_layout.closeDrawer(listView);
    }
}

到了现在,代码完了。
