android-如何使用布局或TextView设置搜索栏缩略图？
作者：互联网
我希望我的搜索栏看起来像这样…
TextView应该随着搜寻栏的拇指而移动…
我尝试过
seek_needle.xml
<?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" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text=""
/>
<ImageView
android:layout_width="25dp"
android:layout_height="fill_parent"
android:src="@drawable/seek_needle"
/>
</LinearLayout>
并在mail.xml中
<SeekBar
android:id="@+id/seekBar1"
android:layout_width="349dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:max="202"
android:layout_weight="80"
android:thumb="@Layout/seek_needle"
> </SeekBar>
该应用程序崩溃
请帮帮我…
这是logcat的输出…

解决方法:
此方法从您的资源中获取一个drawable,在其上方绘制一些文本并返回新的drawable.您需要做的就是为其提供气泡的资源ID,并在顶部显示您想要的文本.然后,您可以在需要的任何地方传递返回的drawable.
public BitmapDrawable writeOnDrawable(int drawableId, String text){
Bitmap bm = BitmapFactory.decodeResource(getResources(), drawableId).copy(Bitmap.Config.ARGB_8888, true);
Paint paint = new Paint();
paint.setStyle(Style.FILL);
paint.setColor(Color.BLACK);
paint.setTextSize(20);
Canvas canvas = new Canvas(bm);
canvas.drawText(text, 0, bm.getHeight()/2, paint);
return new BitmapDrawable(bm);
}
复制自..
Combine image and text to drawable
编辑：
函数调用如下所示：mFreqbar.setThumb(writeOnDrawable(R.drawable.fm_radio_tune_position,mytext));
我将fm_radio_tune_position.png文件保存在res / drawable /中,“ mytext”是我要在该drawable之上编写的字符串
