三星：关闭电源时 InputMethodService 崩溃（NullPointerException）

Question

无法检测 issue.This 三星设备特有的问题。

我在日志中得到的另一件事：

"Unexpected null in startExtractingText : mExtractedText = null, input connection = com.android.internal.view.InputConnectionWrapper"

Answer 1

我已经自己解决了这个问题。在我的例子中，我在重写的方法 setExtractView(View view) 上添加了我的自定义视图。但我并没有先删除视图。

让我解释一下：

@Override
public void setExtractView(View view) {
  // You have to do this if you are not doing so
  view.removeAllViews() ; // This is the line 
  view.addView(yourView) ; // Here you can put your own  Custom view 
  super.setExtractView(view);
}

这对我有用。我希望当您遇到

这样的问题时，这会对您有所帮助
