无法使用 Android Gradle 插件 2.1 生成视图绑定器 java.util.NoSuchElementException
cannot generate view binders java.util.NoSuchElementException with Android Gradle Plugin 2.1
我在我的 Android 项目中使用绑定机制。使用 Android Gradle 插件时一切正常，直到版本 2.0。
几天后，我可以升级到 Android Gradle 插件的 2.1 版。升级时出现以下异常：
java.lang.RuntimeException: failure, see logs for details.

顶部有一个日志文件的引用，但我不知道是哪一个。并且在我的项目中没有引用任何不正确的文件。
有谁知道出了什么问题或者我该如何解决这个错误？
显然，某些与事件和数据绑定相关的内容发生了变化。
到目前为止，我发现这些绑定在迁移到 gradle 2.1
后不起作用
1) EditText 和 onTextChanged:
从 GRADLE 2.1:
开始不工作
<EditText android:onTextChanged="@{binding.onTextChanged}" />
public void onTextChanged(CharSequence s, int start, int before, int count) {}
EDITTEXT && TEXTWATCHER 修复：
<EditText android:addTextChangedListener="@{binding.onTextChanged}" />
public TextWatcher onTextChanged = new SimpleTextWatcher() {
@Override
public void onTextChanged(String newBasic) {}
}
2) SeekBar 和 onProgessChanged:
从 GRADLE 2.1:
开始不工作
<SeekBar android:onProgressChanged="@{viewModel.onSeekbarProgressChanged}" />
public void onSeekbarProgressChanged(@NonNull View _view, int progress, boolean _fromUser) {}
SEEKBAR&& PROGESSCHANGED 的修复：
<SeekBar android:onSeekBarChangeListener="@{viewModel.seekbarChanged}" />
public SeekBar.OnSeekBarChangeListener seekbarChanged = new SimpleProgressChanged() {
@Override
public void onProgressChanged(final int progress) {
.... your code
}
};
其中 SimpleTextWatcher:
public abstract class SimpleTextWatcher implements TextWatcher {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {}
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
@Override
public void afterTextChanged(Editable s) {
onTextChanged(s.toString());
}
public abstract void onTextChanged(String newValue);
}
并且 SimpleProgressChanged：
public abstract class SimpleProgressChanged implements SeekBar.OnSeekBarChangeListener {
public abstract void onProgressChanged(int progress);
@Override
public void onProgressChanged(final SeekBar seekBar, final int progress,
final boolean fromUser) {
onProgressChanged(progress);
}
@Override
public void onStartTrackingTouch(final SeekBar seekBar) {}
@Override
public void onStopTrackingTouch(final SeekBar seekBar) {}
}
与 Android Studio 2.1 Preview 3 一起发布，Android 数据绑定现在具有双向数据绑定。
要实现双向绑定，您只需添加一个字符：
=
编辑文本：
单向绑定
<TextView android:text="@{user.firstName}" .../>
双向绑定
<EditText android:text="@={user.firstName}" .../>
求栏
单向绑定
<SeekBar android:progress="@{viewModel.angle}" .../>
双向绑定
<SeekBar android:progress="@={viewModel.angle}" .../>
无需设置侦听器等它就可以工作。
The only place I've found documentation is on this is at George Mount's (Android Engineer) blog.

}
并且 SimpleProgressChanged：
public abstract class SimpleProgressChanged implements SeekBar.OnSeekBarChangeListener {
public abstract void onProgressChanged(int progress);
@Override
public void onProgressChanged(final SeekBar seekBar, final int progress,
final boolean fromUser) {
onProgressChanged(progress);
}
@Override
public void onStartTrackingTouch(final SeekBar seekBar) {}
@Override
public void onStopTrackingTouch(final SeekBar seekBar) {}
}
与 Android Studio 2.1 Preview 3 一起发布，Android 数据绑定现在具有双向数据绑定。
要实现双向绑定，您只需添加一个字符：
=
编辑文本：
单向绑定
<TextView android:text="@{user.firstName}" .../>
双向绑定
<EditText android:text="@={user.firstName}" .../>
求栏
单向绑定
<SeekBar android:progress="@{viewModel.angle}" .../>
双向绑定
<SeekBar android:progress="@={viewModel.angle}" .../>
无需设置侦听器等它就可以工作。
The only place I've found documentation is on this is at George Mount's (Android Engineer) blog.
