如何在android xml中设计4个可点击的圆形字段

问题描述 投票：0回答：1

这应该是一个非常简单的有趣游戏，您可以选择2种颜色，而您的朋友必须猜测您选择了哪种颜色。我基本上希望我的活动看起来像这样：

enter image description here

每个季度都应该可以通过onClick-Animation进行点击（如果看起来像这样，我想它就不能成为Button了]

使用XML代码获得此结果的最佳方法是什么？我当时在考虑使用ImageViews的ConstraintLayout，但是我得到的不是可点击的圆形，而是可点击区域的矩形。

        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="@id/imgTwo" />

</androidx.constraintlayout.widget.ConstraintLayout>

这可以通过毕加索创建圆形图像来完成，但这感觉更像是一种解决方法，而不是解决方案。

这是诀窍，您可以只使用xml布局来创建它]]

首先在可绘制文件夹中创建4个矢量路径形状

ic_top_left.xml

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="180dp"
    android:height="180dp"
    android:viewportWidth="250"
    android:viewportHeight="250">

    <clip-path
        android:pathData="M0,0h250v250h-250z"/>
    <path

        android:fillColor="#F8675D"/>
  </group>
</vector>

ic_top_right.xml
<vector xmlns:android="http://schemas.android.com/apk/res/android"

        android:fillColor="#8BC34A"/>

</vector>

然后进去activity_main.xml

                android:textStyle="bold"/>

        </LinearLayout>

    </RelativeLayout>


</RelativeLayout>

＆然后为按钮中的按钮创建onClick方法MainActivity.java
package com.softwindevs.circularpiebuttons;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.View;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }


    public void OnClickAndroid(View view) {
        Toast.makeText(this, "Android Button Clicked", Toast.LENGTH_SHORT).show();
    }

    public void OnClickRide(View view) {
        Toast.makeText(this, "Ride Button Clicked", Toast.LENGTH_SHORT).show();
    }

    public void OnClickBugs(View view) {
        Toast.makeText(this, "Bugs Button Clicked", Toast.LENGTH_SHORT).show();
    }

    public void OnClickFitness(View view) {
        Toast.makeText(this, "Fitness Button Clicked", Toast.LENGTH_SHORT).show();
    }
}

＆就是这样，这就是您执行此魔术的方法演示：
