我收到了几个关于我们应用的崩溃报告。
此错误是从Socorro界面提交的,并且是 报告bp-d1b4cdb8-fd3f-457b-9a29-df9192170112。 Socorro-Signature:
java.lang.NullPointerException: Attempt to invoke virtual method ''android.content.res.Resources android.content.Context.getResources()'' on a null object reference: at dnu.afterTextChanged(CommentOperatingFragment.java)

这是我在CommentOperatingFragment中的代码:
@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
…...
mCommentEdt.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence charSequence,
int i, int i1, int i2) {
}
@Override
public void onTextChanged(CharSequence charSequence,
int i, int i1, int i2) {
}
@Override
public void afterTextChanged(Editable editable) {
if (mCommentEdt.getText().toString().isEmpty()) {
mPostTxt.setClickable(false);
mPostTxt.setTextColor(ResourcesCompat.getColor(getContext().getResources(),// Line 252
R.color.article_comment_area_post_color_without_text, null));
} else {
mPostTxt.setClickable(true);
mPostTxt.setTextColor(ResourcesCompat.getColor(getContext().getResources(),
R.color.article_comment_area_post_color_with_text, null));
}
}
});
}
它发生在几个设备上。
6.0.1,SAMSUNG-SM-G935A 6.0.1,SAMSUNG-SM-G890A 6.0,Alco 6.0.1,摩托罗拉,XT1585
我不知道它是否与https://code.google.com/p/android/issues/detail?id=56296
相同我也想知道它是否与getContext位置有关。我在Fragment.onViewCreated中调用它。
但它在源代码中说:此时片段的视图层次结构不会附加到其父级。
答案 0 :(得分:1)
更改
ResourcesCompat.getColor(getContext().getResources(),
R.color.article_comment_area_post_color_with_text, null)
到
ContextCompat.getColor(getActivity(), R.color.article_comment_area_post_color_with_text)
