androidswitch设置_android studio switch控件怎么使用

Ⅰ android中switch控件怎么控制图片的显示隐藏

Android中自带的Switch控件在很多时候总觉得和整体系统风格不符，很多时候，自定义Switch是一种方法。
但其实不用这么麻烦，安卓自带的Switch通过修改一些属性，也可以达到和自定义Switch差不多的一个效果。
个人感觉，Switch的属性设置和其他控件还是有挺大区别的。
实现方式：
底部滑动条，在开关打开状态为绿色，开关关闭状态为灰色
在 res/drawable 文件夹下面，写两个滑动条的底图，通过一个选择器selector进行控制。

Ⅱ android SwitchButton 和CheckBox 怎样设置不可点击，Clickable无效

在线程还在进行时设置按钮不可点击setClickable(false)；
getState()返回该线程的状态；
isAlive()测试线程是否处于活动状态；
view都是setClickable(false); 表示不可点击的；
当然你还可以直接注册一个Touche事件，然后在onTouche里return true;

Ⅲ 安卓switch按钮图标缩小怎么设置

按钮图标，可以使用ImageView 或者ImageButton. 对应三张图片的话，就用三张不同的图片代表就成了。然后实现它们各自的OnClickListener。

Ⅳ android switch控件的注册监听控制

你一定看错了，一个OnClickListener只会对一个view有效，不存在和父控件冲突问题。如果有问题你可以设置setOnClickListener（new
OnClickListener(){
public
void
click(View
v){
log.d("------",
v.getId());
}
}）;
给view设置上id,看看是谁

Ⅳ android开发中switch在切换开/关状态时，先弹出一个dialog（确认/取消）以让用户确认是否切换开/关状态

要实现这种逻辑,方式实在太多了,最简单的就是switch注册点击事件
(不叫你注册onCheckedChanged事件是因为你设置setChecked的时候,又会触发onCheckedChanged)
然后在方法里先弹出一个alertDialog
确定后设置switch.setChecked(true/false)

Ⅵ android 怎样在switch里面设置短信倒计时

1我们首先需要在输入框中输入一个秒数，比如：12，然后获取输入框中的值，显示在一个TextView中；
2点击“开始倒计时”按钮，每隔一秒钟，秒数减1，然后显示在TextView中；
3点击“停止倒计时”按钮，计时器停止运行，当再次点击“开始倒计时”按钮，计时器继续运行。

Ⅶ android 自定义switch样式

修改后的MySwitch控件接口基本与原Switch控件一致，并且除了可支持所有SDK外，增加了2项小功能：
1. 支持用Track背景图片的方式代替Texton Textoff等文字方式表现开关状态
2.支持调整控制Switch的高度
下面贴出Switch修改的关键代码：

/**
* 
* modified from android SDK 14(4.0) android.widget.Switch.
* 
* new feature: 
* <ol>
* <li>support SDK 1 or higher. </li>
* <li>you can use track drawable instead of text to display the changes of off-on state!</li>
* <li>you can control the Switch minimum height. </li>
* </ol>
* 
*
* @see {@link Switch}
* @author Wison
*/
public class MySwitch extends CompoundButton {
// Support track drawable instead of text
private Drawable mTrackOnDrawable;
private Drawable mTrackOffDrawable;

// Support minimum height
private int mSwitchMinHeight;

/**
* Construct a new Switch with a default style determined by the given theme attribute,
* overriding specific style attributes as requested.
*
* @param context The Context that will determine this widget's theming.
* @param attrs Specification of attributes that should deviate from the default styling.
* @param defStyle An attribute ID within the active theme containing a reference to the
* default style for this widget. e.g. android.R.attr.switchStyle.

return mTrackOnDrawable != null && mTrackOffDrawable != null;
}

<attr name="trackOff" format="reference" />

<attr name="switchMinHeight" format="dimension" />


<attr name="thumb" format="reference" />

<attr name="track" format="reference" />

<attr name="textOn" format="string" />

<attr name="textOff" format="string" />

<attr name="thumbTextPadding" format="dimension" />

<attr name="switchTextAppearance" format="reference" />

<attr name="switchMinWidth" format="dimension" />

<attr name="switchPadding" format="dimension" />
</declare-styleable>

Ⅷ android studio switch控件怎么使用

adroid studio switch控件的用法如下：
Switch sc=(Switch)findViewById(R.id.switch1);
sc.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
if (b){
Toast.makeText(getApplicationContext(),"on",Toast.LENGTH_SHORT).show();
}else {
Toast.makeText(getApplicationContext(),"off",Toast.LENGTH_SHORT).show();
}
}
});

Ⅸ AndroidUI控件switch使用方法

首先添加控件：

<Switch

android:id="@+id/sw_sfktmmzf"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginRight="15dp"

android:showText="false"

android:switchMinWidth="50dp"

android:thumb="@drawable/thumb"

android:track="@drawable/track" />

以下是该控件的常用属性：

textOn：控件打开时显示的文字

textOff：控件关闭时显示的文字

thumb：控件开关的图片（设置小圆圈颜色）

track：控件开关的轨迹图片（设置小圆圈背景颜色）

typeface：设置字体类型

switchMinWidth：开关最小宽度

switchPadding：设置开关与文字的空白距离

switchTextAppearance：设置文本的风格

checked：设置初始选中状态

splitTrack：是否设置一个间隙，让滑块与底部图片分隔（API 21及以上）

showText：设置是否显示开关上的文字（API 21及以上）

创建北京控制文件在drawable文件下

1、thumb.xml

<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:drawable="@drawable/green_thumb" android:state_checked="true" />

<item android:drawable="@drawable/gray_thumb" />

颜色文件：

green_thumb.xml

<?xml version="1.0" encoding="utf-8"?>

<shape xmlns:android="http://schemas.android.com/apk/res/android"

android:shape="rectangle" >



<size android:height="@dimen/switch_height" android:width="@dimen/switch_height"/>



<corners android:radius="20dp"/>



<gradient

android:endColor="#eeeeee"

android:startColor="#eeeeee" />

<stroke android:width="1dp"

android:color="@color/home_text1"/>

</shape>

gray_thumb.xml

<?xml version="1.0" encoding="utf-8"?>

<shape xmlns:android="http://schemas.android.com/apk/res/android"

android:shape="rectangle" >



<size android:height="@dimen/switch_height" android:width="@dimen/switch_height"/>



<corners android:radius="20dp"/>



<gradient

android:endColor="#eeeeee"

android:startColor="#eeeeee" />

<stroke android:width="1dp"

android:color="@color/text_color03"/>

</shape>

2、track.xml

<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:drawable="@drawable/green_track" android:state_checked="true" />

<item android:drawable="@drawable/gray_track" />

</selector>

颜色文件：

green_track.xml

<?xml version="1.0" encoding="utf-8"?>

<shape xmlns:android="http://schemas.android.com/apk/res/android"

android:shape="rectangle">



<size android:height="@dimen/switch_height"/>



<corners android:radius="15dp"/>



<gradient

android:endColor="@color/home_text1"

android:startColor="@color/home_text1" />

</shape>

gray_track.xml

<?xml version="1.0" encoding="utf-8"?>

<shape xmlns:android="http://schemas.android.com/apk/res/android"

android:shape="rectangle">



<size android:height="@dimen/switch_height" />



<corners android:radius="15dp" />



<gradient

android:endColor="@color/text_color03"

android:startColor="@color/text_color03" />

</shape>

switch 控件监听事件：

aSwitch.setOnCheckedChangeListener(newCompoundButton.OnCheckedChangeListener() {

 @Override

 public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

 //控制开关字体颜色

 if(isChecked) {

 //打开

 }else{

 //关闭

 }

 }

 });
