问题描述

我试着改变一些Android的组件,如按钮或视图的形状。我可以做的是一个形状分配与OnDraw中,法的背景。好了,它看起来像重塑,但触摸事件仍然会我定义形状以外的地方工作。有没有什么可行的办法来排除我的外形之外触摸?当然,我可以检查鼠标事件的每一个位置,但对于络合剂的形状,我不知道如何检查,如果一个点里面的造型。感谢您的答复。

I tried to change the shape of some Android components like Button or View. What I can do is assign a shape to the background with the onDraw-Method. Well, it looks like reshaped, but the touch-events will still work outside my defined shape. Is there any practicable way to exclude touches outside my shape? Certainly, I could check every position of the mouse-event, but for complexer shapes, I don't know how to check if a point is inside the shape.Thanks for all your replies.

推荐答案

您可以在XML的。例如

You can define the shapes in xml (as you can see here).e.g. :

绘制/ sample_shape.xml:

drawable/sample_shape.xml:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <gradient
        android:startColor="#FFFF0000"
        android:endColor="#80FF00FF"
        android:angle="45"/>
    <padding android:left="7dp"
        android:top="7dp"
        android:right="7dp"
        android:bottom="7dp" />
    <corners android:radius="8dp" />
</shape>

然后就可以使用XML描述为绘制一个的ImageButton

绘制/ samplebutton.xml:

drawable/samplebutton.xml:

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

在你的layoutfile:

in your layoutfile:

<ImageButton
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:background="@drawable/samplebutton">
</ImageButton>
