android中在Button任意位置加圖片效果
https://gundumw100.iteye.com/blog/1205578
通常情況會想到drawableLeft，drawableTop,drawableRight,drawableBotton，這樣是可以做，但隻能在四個位置。
下麵這種辦法可以實現任意位置：
import android.app.Activity;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.text.Html;
import android.text.Spanned;
import android.text.Html.ImageGetter;
import android.widget.Button;
public class demobutton extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageGetter imgGetter = new Html.ImageGetter() {
@Override
public Drawable getDrawable(String source) {
Drawable drawable = null;
drawable = demobutton.this.getResources().getDrawable(
Integer.parseInt(source));
drawable.setBounds(0, 0, drawable.getIntrinsicWidth(),
drawable.getIntrinsicHeight());
return drawable;
}
};
Button btn = (Button) findViewById(R.id.button1);
StringBuffer sb = new StringBuffer();
sb.append("<img src=\"").append(R.drawable.button1).append("\"/>").append("<font color=\"6f6f6f\">按鈕上加圖片效果</font>");;
Spanned span = Html.fromHtml(sb.toString(), imgGetter, null);
btn.setText(span);
sb = null;
}
}
采用Spanned也不是什麼新鮮事了，嗬嗬。這裏隻提供一種思路。不止Button，任意可以顯示文字的View都可以這樣做。
