如何使用佈局或使用TextView設置搜索欄大拇指？

我希望我的搜索欄，看起來像這樣... enter image description here 如何使用佈局或使用TextView設置搜索欄大拇指？

TextView的應搜索欄的拇指移動... 我試着用

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>

並在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>

此應用程序正在崩潰
請幫我...

這裏是logcat的輸出...

http://stackoverflow.com/questions/10722746/add-dynamic-text-over-android-seekbar-thumb - 這可能會幫助，您可以在的onDraw方法 –

這種方法需要從資源繪製，繪製在它上面的一些文字，並返回新繪製。所有你需要做的就是給它一個你的泡泡的資源ID，以及你想要的文本。然後你可以將返回的drawable傳遞到你想要的地方。

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); 
}

從複製.. Combine image and text to drawable

編輯：

函數調用看起來像這樣，mFreqbar.setThumb(writeOnDrawable(R.drawable.fm_radio_tune_position, mytext)); 我遵守了我fm_radio_tune_position.png文件中res/drawable/和 'mytext' 是我想要的字符串寫在答案的翻譯誰使用MonoDroid的/ Xamarin.An是繪製

寫文本意味着我們不需要任何xml文件 – cammando

是的，不需要xml。 –

井@Charan排我試圖實現它，但問題是文本拇指內隱藏和，如果我調整經由提供Ýbm.getHeigh（）/ 2然後的不同值它獲取隱藏它高於母體佈局內 – cammando

功能的頂部機器人如下：

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); 
    }
