不同API中的自定义按钮

Question

我做了一个自定义按钮类来制作方形按钮。按钮在牛轧糖中运行良好，但不会在棒棒糖和棉花糖中显示。我的代码有什么问题？

Java类：

public class SquareButton extends ToggleButton { 

     public SquareButton(Context context) { 
      super(context); 
     } 

     public SquareButton(Context context, AttributeSet attrs) { 
      super(context, attrs); 
     } 

     public SquareButton(Context context, AttributeSet attrs, int defStyleAttr) { 
      super(context, attrs, defStyleAttr); 
     } 
     @Override 
     public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
      super.onMeasure(widthMeasureSpec, heightMeasureSpec); 
      int width = MeasureSpec.getSize(widthMeasureSpec); 
      int height = MeasureSpec.getSize(heightMeasureSpec); 
      int size = width > height ? height : width; 
      setMeasuredDimension(size, size); 

     } 
    } 

XML：

UPD。

如果设置宽度200dp - 它的工作原理。我需要宽度，如高度和高度 - match_parent。

Answer 1

尝试方法改变onMeasure到以下几点：

@Override 
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {   
     int size = widthMeasureSpec > heightMeasureSpec ? heightMeasureSpec : widthMeasureSpec; 
     super.onMeasure(size, size); 

    } 

Answer 2

你可以使用简单的按钮与buttonshape.xml作为按钮

<Button 
android:text="Button" 
android:textColor="#FFFFFF" 
android:textSize="30sp" 
android:layout_width="200dp" 
android:layout_height="200dp" 
android:background="@drawable/buttonshape" 
/> 

的背景中可绘制这段代码粘贴为buttonshape.xml

<?xml version="1.0" encoding="utf-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
android:shape="rectangle" > 
<corners 
android:radius="20dp" 
/> 
<solid 
android:color="#FFFFF" 
/> 
<size 
android:width="200dp" 
android:height="200dp" 
/> 
</shape>
