設置按鈕的文本和背景顏色

通過XML, 可以使用以下的語句:
android:background="#f00000"
android:textColor="#000000"

在運行時可以使用程序代碼:
myIconButton.setBackgroundColor(0xff505050);
myIconButton.setTextColor(0xffffffff);




main.xml

<?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/myIconButton"
        android:drawableLeft="@drawable/icon"
        android:background="#f00000"
        android:textColor="#000000"
        android:text="My Icon Button"
        android:layout_gravity="center_horizontal"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
        </Button>
</LinearLayout>

JAVA

package com.AndroidIconButton;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class AndroidIconButton extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        final Button myIconButton = (Button)findViewById(R.id.myIconButton);
        myIconButton.setOnClickListener(new Button.OnClickListener(){

   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    myIconButton.setBackgroundColor(0xff505050);
    myIconButton.setTextColor(0xffffffff);

   }});
    }
}
