我有一个Android应用程序，当点击侧栏上的一个选项它转到一个片段，然后到另一个片段，它有可点击的单选按钮。单击这些时，它将创建一个弹出窗口，其中包含一些文本字段。
基本上这就是流程的方式，
活动 - ＆gt;片段1 - ＆gt;片段2 - ＆gt; PopupWindow
我在这个PopupWindow上有一个微调器，但当我点击它选择一个值时，它会引发以下异常。我不明白为什么会这样。

这是导致问题的Spinner代码。这是在下面提到的 AssignmentDetailsActivity 类， showDamagedItemEntryPopup（）方法
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);
这是我的方法，可以创建我的 AssignmentDetailsActivity 类
中的弹出窗口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);

Log.d("SK-->", "----------------------------------------------------------");

}
});

对于完全相同的问题花了2天时间：（
我找到的唯一解决方法是在对话框模式下使用微调器
android:spinnerMode="dialog"

很高兴再次帮助您，请查看this问题的答案。您过早地显示弹出窗口，因此您需要delay这样的运行
view.post(new Runnable() {
public void run() {
popupWindow.showAtLocation(view, Gravity.CENTER, 0, 0);
}
});
更新：
或尝试
new Handler(Looper.getMainLooper()).postDelayed(new Runnable() {
@Override
public void run() {
popupWindow.showAtLocation(view, Gravity.CENTER, 0, 0);
}
}, 1000); //Delay one second
