很抱歉,如果标题有点模糊。
我正在为Freelancer开发一款应用程序,除了经过一些测试后客户的投诉外,我几乎完成了它。
我使用PopupWindow代替对话框来编辑上下文设置,如果这有意义的话。我不想过于具体,并且不愿意放弃应用程序概念,我相信客户不会太高兴。
PopupWindow被赋予了从XML扩展的布局的内容视图。在那个布局中有几个EditText小部件。问题是那些EditTexts不会在长按时触发默认的上下文对话框,它提供文本/ IME选择和剪切/复制/粘贴的选项。
我看到一个类似的问题试图获取TouchTrigger或其他东西,如果没有setBackgroundDrawable(),我已经尝试使用一个简单的新ColorDrawable()。它仍然无效。
有没有简单的方法可以在OnLongPressListener中触发系统默认的长按对话框,还是我必须移动天堂和地球来实现它?因为如果是这种情况,我只会为它编写一个Fragment并在事务中将其交换出来。我知道那会有用。
相关代码: 在初始片段内:
RulesDialog dialog;
PopupWindow window;
public void showAddRuleDialog(){
dialog = new RulesDialog();
View view = getView();
window = new PopupWindow(dialog.initViews(this, null), view.getWidth(), view.getHeight(), true);
window.setBackgroundDrawable(new ColorDrawable());
dialog.setRulesDialogListener(new rulesDialogListener(){
@Override
public void onSave(ViewHolder holder) {
addRule(holder);
window.dismiss();
}
@Override
public void onCancel() {
window.dismiss();
}});
int[] location = {0,0};
view.getLocationOnScreen(location);
window.showAtLocation(view, 0, location[0], location[1]);
在RulesDialog中:
public class ViewHolder{
public ViewHolder(View dialogView){
name = (TextView) dialogView.findViewById(R.id.name);
response = (TextView) dialogView.findViewById(R.id.response);
senders = (TextView) dialogView.findViewById(R.id.senders);
sendersAdd = (Button) dialogView.findViewById(R.id.sendersAdd);
sendersEdit = (Button) dialogView.findViewById(R.id.sendersEdit);
timeFrom = (TextView) dialogView.findViewById(R.id.from);
timeFromEdit = (Button) dialogView.findViewById(R.id.timeBeforeEdit);
timeTo = (TextView) dialogView.findViewById(R.id.to);
timeToEdit = (Button) dialogView.findViewById(R.id.timeAfterEdit);
keywords = (TextView) dialogView.findViewById(R.id.keywords);
matchCase = (CheckBox) dialogView.findViewById(R.id.matchCase);
matchAlone = (CheckBox) dialogView.findViewById(R.id.matchAlone);
matchPlural = (CheckBox) dialogView.findViewById(R.id.matchPlural);
cancel = (Button) dialogView.findViewById(R.id.cancel);
save = (Button) dialogView.findViewById(R.id.save);
}
TextView name;
TextView response;
TextView senders;
Button sendersAdd;
Button sendersEdit;
TextView timeFrom;
Button timeFromEdit;
TextView timeTo;
Button timeToEdit;
TextView keywords;
CheckBox matchCase;
CheckBox matchAlone;
CheckBox matchPlural;
Button cancel;
Button save;
}
Activity activity;
ViewHolder holder;
Fragment fragment;
public View initViews(Fragment mFragment, Rule rule){
fragment = mFragment;
activity = fragment.getActivity();
View dialogView = LayoutInflater.from(activity).inflate(R.layout.rules_dialog, null);
holder = new ViewHolder(dialogView);
final TextView senders = holder.senders;
holder.sendersAdd.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
showContacts();
}});
holder.sendersEdit.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
editSenders(senders);
}
});
final TextView timeFrom = holder.timeFrom;
holder.timeFromEdit.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
showTimePickerDialog(timeFrom);
}
});
final TextView timeTo = holder.timeTo;
holder.timeToEdit.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
showTimePickerDialog(timeTo);
}
});
holder.cancel.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
mListener.onCancel();
}});
holder.save.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
mListener.onSave(holder);
}});
if(rule == null)
rule = new Rule();
holder.name.setText(rule.name);
holder.response.setText(rule.response);
holder.senders.setText(rule.senders.toString());
holder.senders.setTag(rule.senders);
holder.keywords.setText(rule.keywords);
holder.matchCase.setChecked(rule.matchCase);
holder.matchAlone.setChecked(rule.matchAlone);
holder.matchPlural.setChecked(rule.matchPlural);
holder.timeFrom.setTag(rule.timeFrom);
holder.timeFrom.setText(Rules.formatTime(rule.timeFrom));
holder.timeTo.setTag(rule.timeTo);
holder.timeTo.setText(Rules.formatTime(rule.timeTo));
return dialogView;
}
答案 0 :(得分:0)
所以我尝试将RulesDialog重写为片段,但效果不佳。当从他们正在操作的碎片调用时,使碎片事务处理正常工作存在问题。
(我知道这不是片段的重点。我现在并不是真的想要编写一个完全模块化的应用程序。我只想提出一个客户会满意的产品。)
我最终将RulesDialog重写为Activity,并使用调用片段中的startActivityForResult()。然后使用setResult()传回已编辑的数据。这一切都很好地协调。
