Seekbar Thumb 问题上的动态文本
Dynamic Text Over Seekbar Thumb Issues
我创建了一系列用于选择值的滑块，当 activity 启动时，所有缩略图及其相应的动态文本出现在同一起点。一旦将滑块向右移动，动态文本就永远不会真正保持在 Thumb 的中心。在某些情况下，当滑块一直向右移动时，动态文本会从屏幕上掉下来。
我想要完成的是所有动态文本都出现在左侧，如左侧的分数滑块（见第一张图片），当在动态文本的最小值和最大值之间的任何位置滑动拇指时应该以拇指为中心（见第二张图片）。当滑块处于最大范围时，所有动态文本应该看起来像 Spares 和 Splits 滑块（见第三张图片）。
这是我的activity_main.xml

我浏览了几个不同的帖子，但似乎找不到任何可以帮助我的东西。如果有人能对此提供一些见解，我将不胜感激。
我也试过下面的代码：
textViewScore.setText(Integer.toString(progress));
double pourcent = progress / (double) seekBarScore.getMax();
int offset = seekBar.getThumbOffset();
int seekWidth = seekBarScore.getWidth();
int val = (int) Math.round(pourcent * (seekWidth - 2 * offset));
int labelWidth = textViewScore.getWidth();
textViewScore.setX(offset + seekBarScore.getX() + val
- Math.round(pourcent * offset)
- Math.round(pourcent * labelWidth/2));
我从这里得到的：Add dynamic text over Android SeekBar thumb
使用以下答案的图像：
试试这个
Point maxSizePoint = new Point();
getWindowManager().getDefaultDisplay().getSize(maxSizePoint);
int maxX = maxSizePoint.x;
textViewScore.setX(textViewScore.getMeasuredWidth() + (val + seekBar.getThumbOffset() / 2) > maxX ? (maxX - textViewScore.getMeasuredWidth() - 16) : val + seekBar.getThumbOffset() / 2);
更新
我试过一个 seekbar 以下是 code 和 output
public class MainActivity extends AppCompatActivity {
int maxX;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SeekBar seekBarScore = findViewById(R.id.seekBarScore);
final TextView textViewScore = findViewById(R.id.textViewScore);
textViewScore.setText("Split Conversions : " + seekBarScore.getProgress());
Point maxSizePoint = new Point();
getWindowManager().getDefaultDisplay().getSize(maxSizePoint);
maxX = maxSizePoint.x;
seekBarScore.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
@Override
public void onProgressChanged(SeekBar seekBar, int progressValue, boolean fromUser) {
int val = (progressValue * (seekBar.getWidth() - 2 * seekBar.getThumbOffset())) / seekBar.getMax();
textViewScore.setText("Split Conversions : " + progressValue);
int textViewX = val - (textViewScore.getWidth() / 2);
int finalX = textViewScore.getWidth() + textViewX > maxX ? (maxX - textViewScore.getWidth() - 16) : textViewX + 16/*your margin*/;
