在res目录下的drawable-mdpi建立xml文件shape.xml,如下图所示:
shape.xml
- <?xml version="1.0" encoding="UTF-8"?>
- <shape
- xmlns:android="http://schemas.android.com/apk/res/android"
- android:shape="rectangle">
- <!-- 填充的颜色 -->
- <solid android:color="#FFFFFF" />
- <!-- 设置按钮的四个角为弧形 -->
- <!-- android:radius 弧形的半径 -->
- <corners android:radius="5dip" />
- <!-- padding:Button里面的文字与Button边界的间隔 -->
- <padding
- android:left="10dp"
- android:top="10dp"
- android:right="10dp"
- android:bottom="10dp"
- />
- </shape>
main.xml
在android:background="@drawable/shape"就使用了shape.xml资源
- <?xml version="1.0" encoding="utf-8"?>
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
- android:orientation="vertical"
- android:layout_width="fill_parent"
- android:layout_height="fill_parent"
- >
- <TextView
- android:layout_width="fill_parent"
- android:layout_height="wrap_content"
- android:text="@string/hello"
- />
- <Button
- android:id="@+id/roundButton"
- android:text=" 圆角按钮 "
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:background="@drawable/shape"
- />
- </LinearLayout>
strings.xml
- <?xml version="1.0" encoding="utf-8"?>
- <resources>
- <string name="hello">Hello World, RoundButtonDemoActivity!</string>
- <string name="app_name">RoundButtonDemo</string>
- </resources>
RoundButtonDemoActivity.java
- package com.android.RoundButtonDemo.activity;
- import android.app.Activity;
- import android.os.Bundle;
- import android.view.View;
- import android.view.View.OnClickListener;
- import android.widget.Button;
- import android.widget.Toast;
- public class RoundButtonDemoActivity extends Activity {
- Button roundButton;
- @Override
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.main);
- roundButton=(Button)findViewById(R.id.roundButton);
- //使用匿名类注册Button事件
- roundButton.setOnClickListener(new OnClickListener()
- {
- public void onClick(View v)
- {
- Toast.makeText(RoundButtonDemoActivity.this, "你点击了圆角按钮",Toast.LENGTH_LONG).show();
- }
- });
- }
- }
