本文介绍了单击微调器时，无法添加窗口，令牌无效错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
当我从侧栏中单击选项时，我有一个android应用程序，它进入一个片段，然后进入另一个具有可单击单选按钮的片段.单击它们时，将创建一个弹出窗口，其中包含一些文本字段.
I have an android application when clicked on an option from a side bar it goes to a fragment, and then into another fragment which has clickable radio buttons. When clicked on these it will create a popup window with some text fields in it.
基本上就是这样，
活动->片段1->片段2-> PopupWindow
Activity --> Fragment 1 --> Fragment 2 --> PopupWindow
我在此PopupWindow上有一个微调框，但是当我单击它以选择一个值时，它将引发以下异常.我不明白为什么会这样.
And i have a spinner on this PopupWindow, but when i click on it to select a value it throws the following exception. I don't understand why this happen.

这是引起问题的Spinner代码.在下面提到的 AssignmentDetailsActivity 类， showDamagedItemEntryPopup()方法
This is the Spinner code that cause the problem. Which is in the below mentioned AssignmentDetailsActivity class, showDamagedItemEntryPopup() method
statusSpinner = (Spinner)popupView.findViewById(R.id.popup_status_spinner);
ArrayAdapter<String> statusSpinnerArrayAdapter = new ArrayAdapter<String>(AssignmentDetailsActivity.this, android.R.layout.simple_spinner_item, statusSpinnerArray);
statusSpinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
statusSpinner.setAdapter(statusSpinnerArrayAdapter);
这是我创建
public void showDamagedItemEntryPopup(RadioButton radioButton, View view){
LayoutInflater layoutInflater = (LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.component_selection_popup, null);
final PopupWindow popupWindow = new PopupWindow(
popupView,
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
// Set popup Animation style
popupWindow.setAnimationStyle(R.style.popupAnimation);
Button buttonClose = (Button)popupView.findViewById(R.id.close_add_component_btn);
// Close button damaged item popop window
buttonClose.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View v) {
popupWindow.dismiss();
}
});
originalAmount = (EditText)popupView.findViewById(R.id.popup_add_component_original_amount);
customerContribution = (EditText)popupView.findViewById(R.id.popup_percentage);
quantity = (EditText)popupView.findViewById(R.id.popup_quantity);
finalAmount = (EditText)popupView.findViewById(R.id.popup_add_component_final_amount);
remarks = (EditText)popupView.findViewById(R.id.popup_add_component_remarks);
// Item Spinner
itemSpinnerArray = new ArrayList<String>();
itemSpinnerArray.add("Select Item");
// Status Spinner
ArrayList<String> statusSpinnerArray = new ArrayList<String>();
statusSpinnerArray.add("FDR");
statusSpinnerArray.add("DR");
statusSpinnerArray.add("SP");
damageComponenetAutoCompleteTextview = (AutoCompleteTextView) popupView.findViewById(R.id.popup_damage_component_item);
damageComponenetAutoCompleteTextview.requestFocus();
ArrayAdapter<String> itemSpinnerArrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, itemSpinnerArray);
damageComponenetAutoCompleteTextview.setThreshold(1);
damageComponenetAutoCompleteTextview.setAdapter(itemSpinnerArrayAdapter);
damageComponenetAutoCompleteTextview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
itemSpinnerValue = (String) parent.getItemAtPosition(position);
Log.d("SK-->", "----------------------------------------------------------");
Log.d("SK-->","itemSpinnerValue: " + itemSpinnerValue);
}
});
statusSpinner = (Spinner)popupView.findViewById(R.id.popup_status_spinner);
ArrayAdapter<String> statusSpinnerArrayAdapter = new ArrayAdapter<String>(AssignmentDetailsActivity.this, android.R.layout.simple_spinner_item, statusSpinnerArray);
statusSpinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
statusSpinner.setAdapter(statusSpinnerArrayAdapter);
//Creating a text Watcher
TextWatcher textWatcher = 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) {
//here, after we introduced something in the EditText we get the string from it
//String answerString = originalAmount.getText().toString();
if (originalAmount.getText().toString().trim().equals("") || customerContribution.getText().toString().trim().equals("")
|| quantity.getText().toString().trim().equals("")) {
// Error , one or more editText are empty
}
else
{
calculateFinalAmount();
}
//and now we make a Toast
//modify "yourActivity.this" with your activity name .this
//Toast.makeText(yourActivity.this,"The string from EditText is: "+answerString,0).show();
}
};
// Adding Text Watcher to our text boxes
originalAmount.addTextChangedListener(textWatcher);
customerContribution.addTextChangedListener(textWatcher);
quantity.addTextChangedListener(textWatcher);
// Show the popup
popupWindow.showAtLocation(view, Gravity.CENTER, 0, 0);
}
public void onSaveItem(View view) {
statusSpinnerValue = (String) statusSpinner.getItemAtPosition(statusSpinner.getSelectedItemPosition());
statusSpinnerValue = "ABC";
itemSpinnerValue = "TEST ITEM";
originalAmount.setText("50");
customerContribution.setText("25");
quantity.setText("1");
if(itemSpinnerValue.matches("Select Item") ||itemSpinnerValue.matches("") || statusSpinnerValue.matches("") || originalAmount.getText().toString().matches("") || customerContribution.getText().toString().matches("") ||
quantity.getText().toString().matches("")){
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("ERROR!");
builder.setMessage("Please Fill the Required Fields.")
.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//do things
dialog.dismiss();
}
});
AlertDialog alert = builder.create();
alert.show();
}
else{
Log.e("TEST", "Check Passed");
Date date = new Date();
if(mDbHandler.itemAlreadyExist(reportID,"item_name", itemSpinnerValue, "DamageComponent") == false){
mDbHandler.addDamageComponent(reportID, itemSpinnerValue, statusSpinnerValue, originalAmount.getText().toString(), Double.parseDouble(customerContribution.getText().toString()),
Integer.parseInt(quantity.getText().toString()), finalAmount.getText().toString(), remarks.getText().toString());
mDbHandler.updateReport(reportID, date.toString(), "time_last_modified");
Toast.makeText(this,"Component Successfully Added",Toast.LENGTH_SHORT).show();
}
else{
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("ERROR!");
builder.setMessage("Item Already Exist.")
.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//do things
dialog.dismiss();
}
});
AlertDialog alert = builder.create();
alert.show();
}
mDbHandler.close();
}
}
推荐答案
花了2天时间解决同样的问题:(
Spent 2 days for exactly the same problem :(
我发现的唯一解决方法是在对话框模式下使用微调器
The only workaround I find is to use spinner in dialog mode
android:spinnerMode="dialog"
