读取短信数据库放到ListView中显示

在布局文件中加入ListView布局

<?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="com.example.e5.duanxin.MainActivity">


    <ListView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:id="@+id/lv"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true" />
</RelativeLayout>

新建一个item布局文件，内容可根据具体需求编辑
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">

    <TextView
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:text="Large Text"
        android:id="@+id/textView2"
        android:textColor="#aa5599" />
    <TextView
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:id="@+id/textView"
        android:text="body"
        android:textColor="#FF5533" />

</LinearLayout>

　　 ListView lv;
    List<Person> personsInfos;

在AndroidManifest.xml文件中配置权限

 <uses-permission android:name="android.permission.READ_SMS"></uses-permission>

　　

在MainActivity中声明一个listView布局和一个List集合用于存放数据

得到ListView布局，和创建List集合对象

获得ContentResolver的对象

lv=(ListView) findViewById(R.id.lv);
personsInfos=new ArrayList<Person>();

ContentResolver resolver= getContentResolver();

 

找到手机应用程序"短信"的Uri

Uri uri = Uri.parse("content://sms/");

 

创建cursor类的对象，将查询得到的数据放到cursor中，通过moveToNext()将数据分别放入已经建好的Person类中
最后关闭cursor

Cursor cursor=resolver.query(uri,null,null,null,null);
while (cursor.moveToNext()){
    Person person=new Person();
    person.setBody( cursor.getString(cursor.getColumnIndex("body")));

    person.setType( cursor.getString(cursor.getColumnIndex("address")));
    personsInfos.add(person);

}
    cursor.close();

创建BaseAdapter解析器

 

创建一个内部类，继承BaseAdapter接口,并实现其抽象类

private class MyAdapter extends BaseAdapter{



    @Override
    public int getCount() {

        return personsInfos.size() ;

    }

    @Override
    public Object getItem(int position) {
        return position;
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View view=View.inflate(MainActivity.this,R.layout.list_itme,null);
        TextView tv_b= (TextView)view. findViewById(R.id.textView);
        TextView tv_t= (TextView)view. findViewById(R.id.textView2);
        tv_t.setText(personsInfos.get(position).getType());
        tv_b.setText(personsInfos.get(position).getBody());
        return view;
    }
}

　　将适配器加载的ListView布局里

lv.setAdapter(new MyAdapter());
