AutoCompleteTextView用法总结【Android】

以下是对AutoCompleteTextView的一些小小总结



1.AutoCompleteTextView用ArrayAdapter适配器:

布局文件:

main.xml

<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"    tools:context=".MainActivity" >    <AutoCompleteTextView        android:id="@+id/actv"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:completionThreshold="1" /></RelativeLayout>

java文件:

package com.succ7.autocompletiondemo;import android.app.Activity;import android.os.Bundle;import android.widget.ArrayAdapter;import android.widget.AutoCompleteTextView;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);//主代码String[] arrs = new String[]{"abc","adaadfa","aadfdfda","adsfadf"};ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line,arrs);AutoCompleteTextView actv = (AutoCompleteTextView) findViewById(R.id.actv);actv.setAdapter(adapter);}}

2.AutoCompleteTextView用CursorAdapter适配器:

布局文件:

<?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="vertical" >        <AutoCompleteTextView            android:id="@+id/actv_contact_number"            android:layout_width="match_parent"            android:hint="请输入号码"            android:layout_height="wrap_content"            android:completionThreshold="1"            android:background="@drawable/conversation_detail_input_selector" /></LinearLayout>

<?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="wrap_content"    android:orientation="vertical" >    <TextView        android:id="@+id/tv_select_contact_name"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="name"        android:textSize="22sp" />    <TextView        android:id="@+id/tv_select_contact_address"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="address"        android:textColor="#00ff00"        android:textSize="18sp" /></LinearLayout>

java文件:

package com.succ7.smartsms;import android.app.Activity;import android.content.Context;import android.database.Cursor;import android.os.Bundle;import android.provider.ContactsContract.CommonDataKinds.Phone;import android.view.View;import android.view.ViewGroup;import android.widget.AutoCompleteTextView;import android.widget.CursorAdapter;import android.widget.FilterQueryProvider;import android.widget.TextView;public class CopyOfNewSmsActivity extends Activity {private AutoCompleteTextView actv_contact_number;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_new_sms);setTitle("新建信息");init();}private void init() {actv_contact_number = (AutoCompleteTextView) findViewById(R.id.actv_contact_number);NewMsgCursorAdapter adapter = new NewMsgCursorAdapter(this, null);actv_contact_number.setAdapter(adapter);adapter.setFilterQueryProvider(new FilterQueryProvider() {//当输入框中的内容发生变化时回调上方法@Overridepublic Cursor runQuery(CharSequence constraint) {String[] projection = new String[]{"display_name","data1","_id"};Cursor cursor = getContentResolver().query(Phone.CONTENT_URI, projection, "data1 like ?", new String[]{constraint+"%"}, null);//将cursor对象返回给adapterreturn cursor;}});}//为自动完成的输入框定义的cursoradapterclass NewMsgCursorAdapter extends CursorAdapter{public NewMsgCursorAdapter(Context context, Cursor c) {super(context, c);// TODO Auto-generated constructor stub}@Overridepublic CharSequence convertToString(Cursor cursor) {return cursor.getString(1);}@Overridepublic void bindView(View view, Context context, Cursor cursor) {String name = cursor.getString(0);String address = cursor.getString(1);TextView tv_select_contact_name = (TextView) view.findViewById(R.id.tv_select_contact_name);TextView tv_select_contact_address = (TextView) view.findViewById(R.id.tv_select_contact_address);tv_select_contact_name.setText(name);tv_select_contact_address.setText(address);}@Overridepublic View newView(Context context, Cursor cursor, ViewGroup parent) {View view = View.inflate(context, R.layout.item_select_contact, null);return view;}}}
