我有一个带有可绘制对象的自定义搜索栏，它工作正常，我正在尝试在搜索栏上制作有关用户操作的工具提示文本，有没有不使用第三方库的方法，我已经在下面发布了我正在使用的代码用于自定义搜索栏

我还附上了我希望在下面实现的示例进度工具提示

任何引用或解决方案将不胜感激

implementation "com.android.support:appcompat-v7:${android_support_version}"

seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int progressValue, boolean fromUser) {
                seekBar.setThumb(getThumb(progressValue));
                TooltipCompat.setTooltipText(seekBar, String.valueOf(progressValue));
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {
                //Do nothing
            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {
                //Do nothing
            }
        });

 private Drawable getThumb(int progress) {
        View thumbView = LayoutInflater.from(getActivity()).inflate(R.layout.seekbar_tv, null, false);
        ((TextView) thumbView.findViewById(R.id.tvProgress)).setText(progress + "");
        thumbView.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
        Bitmap bitmap = Bitmap.createBitmap(thumbView.getMeasuredWidth(), thumbView.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bitmap);
        thumbView.layout(0, 0, thumbView.getMeasuredWidth(), thumbView.getMeasuredHeight());
        thumbView.draw(canvas);
        return new BitmapDrawable(getResources(), bitmap);
    }

最佳答案

您应该拥有自定义的 textview 并更改 onProgressChanged 中的文本。

够了吗？ ==> 没有

您需要更改 textview 的 x 坐标，以更改它的位置以与 seekbar 位置兼容。

代码证明:

@Override
public void onProgressChanged(SeekBar seekBar, int progress,
        boolean fromUser) {

    yourTextView.setText(progress + " miles");
    // Get the thumb bound and get its left value
    int x = seekBar.getThumb().getBounds().left;
    // set the left value to textview x value
    yourTextView.setX(x);
}
