android常用控件【JAVA】

一.ToggleButton按钮控件

事例：用一个ToggleButton按钮控制灯泡的开关，即转换图片

代码：

1.activity_main.xml

<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"  android:orientation="vertical">    <ToggleButton        android:id="@+id/toggleButton1"        android:checked="false"        android:textOn="开"        android:textOff="关"        android:layout_width="match_parent"        android:layout_height="wrap_content" />    <ImageView        android:id="@+id/imageView1"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:background="@drawable/off"        /></LinearLayout>

2.MainActivity.java

package com.example.togglebuttontest;import android.app.Activity;import android.os.Bundle;import android.view.Menu;import android.view.MenuItem;import android.widget.CompoundButton.OnCheckedChangeListener;import android.widget.CompoundButton;import android.widget.ImageView;import android.widget.ToggleButton;public class MainActivity extends Activity implements OnCheckedChangeListener{private ToggleButton tb;private ImageView img;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);tb=(ToggleButton) findViewById(R.id.toggleButton1);img=(ImageView) findViewById(R.id.imageView1);tb.setOnCheckedChangeListener(this);}@Overridepublic void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {// 当tb被点击时执行img.setBackgroundResource(isChecked?R.drawable.on:R.drawable.off);}}

需要用到的图片：

二.AutoCompleteTextView和MultiAutoCompleteTextView控件

事例：输入3个字符即实现文本匹配

1.activity_main.xml

<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"    android:orientation="vertical">    <AutoCompleteTextView        android:completionThreshold="3"        android:id="@+id/autoCompleteTextView1"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:hint="@string/hint_name" >    </AutoCompleteTextView>    <MultiAutoCompleteTextView        android:id="@+id/multiAutoCompleteTextView1"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:hint="@string/hint_name2" >    </MultiAutoCompleteTextView></LinearLayout>

2.MainActivity.java

package com.example.second;import android.app.Activity;import android.os.Bundle;import android.widget.ArrayAdapter;import android.widget.AutoCompleteTextView;import android.widget.MultiAutoCompleteTextView;public class MainActivity extends Activity {private AutoCompleteTextView acTextView;private String[] res={"beijing1","beijing2","beijing3","shanghai1","shanghai2"};private MultiAutoCompleteTextView macTextView;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);acTextView=(AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1);ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,res);acTextView.setAdapter(adapter);macTextView=(MultiAutoCompleteTextView) findViewById(R.id.multiAutoCompleteTextView1);macTextView.setAdapter(adapter);macTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());}}

三.MarqueeText即走马灯效果

事例：两个TextView当每个字数很多时能够实现走马灯效果

1.activity_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="${relativePackage}.${activityClass}" >    <com.example.marqueentextviewdemo.MarqueeText        android:id="@+id/textview1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:singleLine="true"        android:ellipsize="marquee"        android:focusable="true"        android:textColor="#069"        android:focusableInTouchMode="true"        android:text="@string/hello_world" />         <com.example.marqueentextviewdemo.MarqueeText         android:layout_below="@id/textview1"         android:layout_marginTop="10dp"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:singleLine="true"        android:textColor="#ababab"        android:ellipsize="marquee"        android:focusable="true"        android:focusableInTouchMode="true"        android:text="@string/hello_world" /></RelativeLayout>

2.MarqueeText.java

package com.example.marqueentextviewdemo;import android.content.Context;import android.util.AttributeSet;import android.widget.TextView;public class MarqueeText extends TextView {public MarqueeText(Context context, AttributeSet attrs, int defStyle) {super(context, attrs, defStyle);// TODO Auto-generated constructor stub}public MarqueeText(Context context, AttributeSet attrs) {super(context, attrs);// TODO Auto-generated constructor stub}public MarqueeText(Context context) {super(context);// TODO Auto-generated constructor stub}@Overridepublic boolean isFocused() {return true;}}

四.单选框RadioGroup及复选框CheckBox以及Button按钮

1.activity_main.xml

<LinearLayout     xmlns:tools="http://schemas.android.com/tools"    xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    >    <CheckBox        android:id="@+id/checkBox1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:checked="false"        android:text="游泳" />    <RadioGroup        android:id="@+id/radioGroup1"        android:orientation="horizontal"        android:layout_width="wrap_content"        android:layout_height="wrap_content" >        <RadioButton            android:id="@+id/radio0"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:checked="true"            android:text="男" />        <RadioButton            android:id="@+id/radio1"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="女" />    </RadioGroup>    <Button        android:id="@+id/button1"        android:layout_weight="3"        android:layout_gravity="center"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="Button" />    <Button        android:id="@+id/button2"        android:layout_weight="5"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="Button" /></LinearLayout>
