Seekbar Thumb问题上的动态文本
我创建了一系列用于选择值的滑块，当活动开始时，所有拇指及其相应的动态文本都出现在同一起点。一旦将滑块向右移动，动态文本就永远不会真正停留在Thumb的中心。在某些情况下，将滑块一直移到最右边时，动态文本将从屏幕上掉出来。
我要完成的是所有动态文本都像左侧的“得分滑块”一样出现在左侧（请参见第一张图片），当将拇指滑动到最小值和最大值之间的任何位置时，动态文本应为居中于Thumb（请参见第二个图像）。当滑块处于最大范围时，所有动态文本应看起来像“备用”和“拆分”滑块（请参见第三张图片）。
这是我的activity_main.xml

我经历了几篇不同的文章，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识，我将不胜感激。
我还尝试了以下代码：
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
使用下面的答案获得的图像：
1 个答案:
答案 0 :(得分：0)
尝试
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
我尝试过的单个seekbar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*/;
textViewScore.setX(finalX < 0 ? 16/*your margin*/ : finalX);
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
}
}
