android - 如何使用布局或 TextView 设置搜索栏拇指？

Question

我希望我的搜索栏看起来像这样...... 在此处输入图像描述

TextView 应该随着搜索栏的拇指移动......我试过了

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

  <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>

因为这个应用程序崩溃

此方法从您的资源中获取一个可绘制对象，在其上绘制一些文本并返回新的可绘制对象。您需要做的就是给它您的气泡的资源 ID，以及您想要在顶部的文本。然后，您可以将返回的可绘制对象传递到您想要的任何地方。

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..将图像和文本组合到drawable

编辑：

函数调用看起来像这样，mFreqbar.setThumb(writeOnDrawable(R.drawable.fm_radio_tune_position, mytext)); 我保存了我的fm_radio_tune_position.png文件，res/drawable/' mytext'是我想写在那个可绘制对象之上的字符串

为使用 MonoDroid / Xamarin.Android 的人翻译的答案功能如下：

public BitmapDrawable WriteOnDrawable(int drawableId, String text)
    {
        Bitmap bm = BitmapFactory.DecodeResource(Resources, drawableId).Copy(Bitmap.Config.Argb8888, true);

        Paint paint = new Paint();
        paint.SetStyle(Paint.Style.Fill);
        paint.Color = Color.Black;
        paint.TextSize = 20;

        Canvas canvas = new Canvas(bm);
        canvas.DrawText(text, 0, bm.Height / 2, paint);

        return new BitmapDrawable(bm);
    }
