android-如何使用布局或TextView设置搜索栏缩略图？

概述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<?xmlversion="1.0"encoding="utf-8"?><LinearLayoutxmlns:android="http://schemas.android.com/apkes/android"android:layout_width="match_parent&qu

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
