Android自定义Button按钮

Android自定义Button按钮主要可以分成两种形式:

1.通过自定MyButton类来继承Button,将所有效果在类中实现.

2.通过xml文件来改变Button的样式和颜色.

今天我就先讲通过xml文件,稍后封装自定义Button类再补上.

TestcActivity

[html]
package com.example.blueapp;

import android.app.Activity;
import android.os.Bundle;

public class TestcActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.testc);
    }
}

package com.example.blueapp;

import android.app.Activity;
import android.os.Bundle;

public class TestcActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  setContentView(R.layout.testc);
}
}
