如何在按下时突出显示图像按钮

我希望自己的图像按钮能够自我照亮，就像按下“正常”按钮时的正常发光效果。所以我试图把图像放进去，但是后面有一个“灰色区域”，所以我将它变成了透明的，所以只有图像会显示，但是然后发光效果消失了。有针对这个的解决方法吗？ :)如何在按下时突出显示图像按钮

请参阅imgur图像作为示例 - Example image here

如果是“硬”我可以用图像背后的灰色区域居住，但它可能然后使它绿色用相同的高亮效果？

我应该把代码放在MainActivity中还是我的片段java？片段的Java

您可以使用** ImageView **代替ImageButton吗？ –

可能重复[Android按钮选择并按可绘制]（http://stackoverflow.com/questions/13443534/android-button-select-and-press-drawable） –

也许这...基本上，你需要一个选择器说当按钮被按下时。 https://stackoverflow.com/questions/5624609/android-how-to-make-a-drawable-selector –

把要强调以上鲜艳颜色的查看和设置视图等于View.GONE的知名度ImageView的。现在与您的ImageButton

((ImageButton)findViewById(R.id.myImageBtn)).setOnTouchListener(new OnTouchListener() { 

    @Override 
    public boolean onTouch(View v, MotionEvent event) { 
     switch (event.getAction()) { 
     case MotionEvent.ACTION_DOWN: { 
      myView.setVisibility(View.VISIBLE); 
      break; 
     } 
     case MotionEvent.ACTION_UP: 
      myView.setVisibility(View.GONE); 
      break; 
      // Your action here on button click 

     case MotionEvent.ACTION_CANCEL: { 
      myView.setVisibility(View.GONE); 
      break; 
     } 
     } 
     return true; 
    } 
});

嗨谢谢你帮助我！我应该在哪里将代码放在Mainactivity或我的片段代码中？不知道在哪里放置公共布尔值.. – Tim

@Tim OnTouchListener（）是与onTouch方法的接口。所以只需创建它的新实例。顺便检查我的答案这是你的问题的正确答案 –

Ty mate !!有效：） – Tim

您可以用户选择器drawable和3个不同的按钮drawables为每个状态。创建这些文件可绘制文件夹，并添加此行按键的android：背景= “@绘制/ button_selector”

button_selector.xml

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

camera_button_hold.xml

<?xml version="1.0" encoding="utf-8"?> 
    <shape xmlns:android="http://schemas.android.com/apk/res/android" 
     android:shape="oval"> 
     <solid 
      android:color="#673ab7"/> 
    </shape>

camera_button_normal.xml

<?xml version="1.0" encoding="utf-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="oval"> 
    <stroke 
     android:width="2dp" 
     android:color="#673ab7"/> 
</shape>
