Autocompletetextview按输入键过滤

我使用autocompletetextview和SimpleCursorAdapter从sqlite获取数据。我想通过输入的密钥启动它的下拉列表。在我的autocompletetextview中,列表不会按输入文本显示或过滤。

例如 如果用户输入“an”,则在此列表中将显示以“an”开头的所有文本。

在Java中

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.new);

        txtPNo = (AutoCompleteTextView) findViewById(R.id.txtSTo);        

        mDbHelper = new DBAdapter(this);
        mDbHelper.open();

        SimpleCursorAdapter notes = fillToData();
        txtPNo.setAdapter(notes); 
}

    private SimpleCursorAdapter fillToData() {
        Cursor c = mDbHelper.getName();
        startManagingCursor(c);
        String[] from = new String[] {DBAdapter.Name,DBAdapter.No1};
        int[] to = new int[] {R.id.txtName,R.id.txtNo1};

        Log.d(TAG, "cursor.getCount()=" + c.getCount());
        SimpleCursorAdapter notes =
            new SimpleCursorAdapter(this, R.layout.autocomplete, c, from,
to);

        return notes;
    } 

在new.xml中

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:background="#ffffff"
    >
   <AutoCompleteTextView android:id="@+id/txtSTo"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textSize="18sp"
        android:textColor="#000000"     
        android:hint="To"       
        android:completionThreshold="1" 
        android:selectAllOnFocus="true"  
        android:layout_alignParentTop = "true"
        android:layout_alignParentLeft="true"/>       
</RelativeLayout>

在autocomplete.xml

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="wrap_content"
    android:stretchColumns="0" android:padding="5dp"> 
    <TableRow android:padding="5dp">
        <LinearLayout android:orientation="vertical">
            <TextView android:id="@+id/txtName"
                xmlns:android="http://schemas.android.com/apk/res/android"
                android:textColor="#000000"   
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"/> 
            <TextView android:id="@+id/txtNo1"
                xmlns:android="http://schemas.android.com/apk/res/android"
                android:textColor="#000000"   
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"/> 
        </LinearLayout>
    </TableRow>
</TableLayout>

如何实现刚刚过滤的列表?

答案 0 :(得分:0)

    txtPNo = (AutoCompleteTextView) findViewById(R.id.txtSTo);        

    mDbHelper = new DBAdapter(this);
    mDbHelper.open();

    SimpleCursorAdapter notes = fillToData();
    txtPhoneNo.setAdapter(notes); 

嗯,如果你只是复制并粘贴你的代码......

问题是变量名称。

txtPNo != txtPhoneNo
