Button图文混排的按钮

 

    按钮上可以设置背景图片，也可以自定义按钮，这里介绍按钮上文字和图片混合排列的效果。

一、建立工程

二、activity_main.xml中代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <LinearLayout 
         android:layout_width="match_parent"
            android:layout_height="120dp"
            android:orientation="horizontal" >
        <Button 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:drawableTop="@drawable/star"
            android:text="按钮1"
            />
        <Button 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:drawableTop="@drawable/star"
            android:drawablePadding="30dp"
            android:text="按钮2"
            />
        <Button 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:drawableTop="@drawable/star"
            android:drawableLeft="@drawable/star"
            android:text="按钮3"
            />
        <Button 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:drawableRight="@drawable/star"
            android:drawablePadding="30dp"
            android:text="按钮4"
            />

    </LinearLayout>
        <Button 
            android:layout_width="200dp"
            android:layout_height="200dp"
            android:id="@+id/button"
            android:layout_marginTop="10dp"
            />

</LinearLayout>

View Code

三、MainActivity.java中代码

package com.study.imagebutton;

import android.os.Bundle;
import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.text.SpannableString;
import android.text.Spanned;
import android.text.style.DynamicDrawableSpan;
import android.text.style.ImageSpan;
import android.view.Menu;
import android.widget.Button;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        Button button = (Button)this.findViewById(R.id.button);
        SpannableString spannableStringLeft = new SpannableString("Left");
        Bitmap bitmapLeft = BitmapFactory.decodeResource(getResources(), R.drawable.image_left);
        ImageSpan imageSpanLeft = new ImageSpan(bitmapLeft, DynamicDrawableSpan.ALIGN_BOTTOM);
        spannableStringLeft.setSpan(imageSpanLeft, 0, 4, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        
        SpannableString spannableStringRight = new SpannableString("Right");
        Bitmap bitmapRight = BitmapFactory.decodeResource(getResources(), R.drawable.image_right);
        ImageSpan imageSpanRight = new ImageSpan(bitmapRight, DynamicDrawableSpan.ALIGN_BOTTOM);
        spannableStringRight.setSpan(imageSpanRight, 0, 5, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        button.append(spannableStringLeft);
        button.append("我的按钮");
        button.append(spannableStringRight);
        
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
    
}

View Code

四、效果图

按钮4的文字本来不是竖着的，是因为控件不够了，所以显示为竖着的形式。

五、按钮图片
