我正在尝试根据在 EditText 中输入的数字来更改 SeekBar 的进度，但由于某种原因 EditText 值变为到最大，我无法在 SeekBar 中滑动拇指.

I am trying to change the progress of a SeekBar based on the number entered in an EditText but for some reason the EditText value goes to the max and I can't slide the thumb in the SeekBar.

我希望实现的目标:如果在 EditText 中输入的值介于 70 和 190 之间(包括两个数字)，则将 SeekBar 的进度更改为该值.

What I am looking to achieve: If the value entered in the EditText anywhere between 70 and 190 (including both number) change the progress of the SeekBar to that value.

部分 Java 代码:

Partial Java code:

etOne = (EditText) findViewById(R.id.etSyst); etOne.addTextChangedListener(new TextWatcher() { public void afterTextChanged(Editable s) { String filtered_str = s.toString(); if (Integer.parseInt(filtered_str) >= 70 && Integer.parseInt(filtered_str) <= 190) { sbSyst.setProgress(Integer.parseInt(filtered_str)); } } public void beforeTextChanged(CharSequence s, int start, int count, int after) {} public void onTextChanged(CharSequence s, int start, int before, int count) {} });

部分 XML:

<SeekBar android:id="@+id/syst_bar" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_margin="10dp" android:progress="0" android:max="120" android:progressDrawable="@drawable/progress_bar" android:secondaryProgress="0" android:thumb="@drawable/thumb_state" />

我给每个值加 70，因为 SeekBar 从 0 开始，但我希望它从 70 开始.

I add 70 to each value, because SeekBar starts at 0, but I want it to start at 70.

使用上面的代码后是这样的:

After using the above code, this is what it looks like:

SeekBar 是最大数，EditText 也是最大数.

The SeekBar is at the maximum number and the EditText is at the maximum as well.

推荐答案

etOne = (EditText) findViewById(R.id.etSyst); etOne.addTextChangedListener(new TextWatcher() { public void afterTextChanged(Editable s) { int i = Integer.parseInt(s.toString()); if (i >= 70 && i <= 190) { sbSyst.setProgress( i - 70); // This ensures 0-120 value for seekbar } } public void beforeTextChanged(CharSequence s, int start, int count, int after) {} public void onTextChanged(CharSequence s, int start, int before, int count) {} });
