Android 按下时更改按钮背景

我想更改按钮单击时的背景。我试着用选择器。但它不起作用。下面是选择器（add_grp_slctr.xml）：

<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>

</selector>

和按钮：

       <Button
            android:id="@+id/addGrpBtn"
            android:layout_width="55dp"
            android:layout_height="45dp"
            android:layout_gravity="center"
            android:background="@drawable/add_grp_slctr"
            android:onClick="addGrpDialogOpen" />

<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>

</selector>

添加和添加是图像（png）。

使用您的选择器

<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>

</selector>

像这样更改代码

 <?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
 <item android:state_focused="true" android:drawable="@drawable/add_grp_d"/>
 <item android:state_pressed="true" android:drawable="@drawable/add_grp" />
 <item android:drawable="@drawable/add_grp_d" /> 
 </selector>

<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>

</selector>

我的代码

<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>

</selector>

使用选择器

<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>

</selector>

像这样更改代码

 <?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
 <item android:state_focused="true" android:drawable="@drawable/add_grp_d"/>
 <item android:state_pressed="true" android:drawable="@drawable/add_grp" />
 <item android:drawable="@drawable/add_grp_d" /> 
 </selector>

<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>

</selector>

我的代码

<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>

</selector>

我认为您应该稍微更改一下选择器。

检查这个答案。

我认为你应该稍微改变一下选择器。

<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>

</selector>

检查这个答案。

检查一下答案。此外，仅当您使用硬件键盘对焦按钮时，按钮对焦状态才起作用。

<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>

</selector>

至于你的情况

<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>

</selector>

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
     <item android:state_pressed="false" android:state_selected="false" android:drawable="@drawable/button_default"/>
     <item android:state_pressed="true" android:state_selected="false" android:drawable="@drawable/button_default" />
     <item android:state_pressed="false" android:state_selected="true" android:drawable="@drawable/button_selected"/>
     <item android:state_pressed="true" android:state_selected="true" android:drawable="@drawable/button_selected" />
     <item android:drawable="@drawable/button_selected" /> 
</selector>

检查一次。此外，仅当您使用硬件键盘对焦按钮时，按钮对焦状态才起作用。 至于你的情况

<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>

</selector>

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
     <item android:state_pressed="false" android:state_selected="false" android:drawable="@drawable/button_default"/>
     <item android:state_pressed="true" android:state_selected="false" android:drawable="@drawable/button_default" />
     <item android:state_pressed="false" android:state_selected="true" android:drawable="@drawable/button_selected"/>
     <item android:state_pressed="true" android:state_selected="true" android:drawable="@drawable/button_selected" />
     <item android:drawable="@drawable/button_selected" /> 
</selector>

如果您只想更改按钮的颜色，而不是传递cuastom XML文件，则可以尝试以下方法

<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>

</selector>

Button lineColorCode = (Button)findViewById(R.id.button1);

现在在按钮的单击事件中使用以下代码

<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>

</selector>

int color = Color.parseColor("#AE6118"); //The color u want             
lineColorCode.setColorFilter(color);

我尝试了一个类似的代码，默认情况下为白色，单击按钮时为黑色：

<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>

</selector>

//****这是btn\u选择器，将在可绘制文件夹中声明***

<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>

</selector>

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true"
          android:drawable="@android:color/black" /> <!-- pressed -->
    <item android:drawable="@android:color/white" /> <!-- default -->
</selector>
