按输入键过滤的自动完成文本视图

发布于 2024-09-01 18:44:59 字数 2840 浏览 2 评论 0原文

我使用 autocompletetextview 和 SimpleCursorAdapter 从 sqlite 获取数据。我想通过输入的键启动其下拉列表。在我的自动完成文本视图中,列表未显示或按输入文本过滤。

例如, 如果用户输入“an”,则所有以“an”开头的文本都会在此列表中看到。

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中

<?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>

如何实现获取刚刚过滤的列表?

I use autocompletetextview with SimpleCursorAdapter to get data from sqlite. I'd like to get its drop down list started by the entered key. In my autocompletetextview, the list is not shown or filtered by input text.

eg,
If user enter "an", all text started with "an" will be seen in this list.

In Java

    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;
    } 

In new.xml

<?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>

In 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>

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

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

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

嗯,如果你只是复制粘贴你的代码......

问题是变量名。

txtPNo != txtPhoneNo


AutoCompleteTextView

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

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

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

Umm, if you just copy-n-pasted your code...

The issue is the variable name.

txtPNo != txtPhoneNo


AutoCompleteTextView
