android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application
将语句1改为语句2即可！如下
语句1：context = getActivity().getApplicationContext();
语句2：context = getActivity();

以下代码用于在PopupWindow中实现长按EditText弹出spinner列表
final String[] options={"全选","剪切","复制","粘帖"};
final Spinner spinner = (Spinner) view.findViewById(R.id.spinner);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(context,android.R.layout.simple_spinner_item,options);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
ToastUtil.show("you select >> " + options[position]);
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
popWin.setTouchInterceptor(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
editText.setOnLongClickListener(new OnLongClickListener() {
public boolean onLongClick(View v) {
Logger.v(TAG, "editText long click");
// InputMethodManager imm = (InputMethodManager) context
// .getSystemService(Context.INPUT_METHOD_SERVICE);
// imm.showInputMethodPicker();
spinner.performClick();
return false;
}
});
return false;
}
});使用反射机制调用系统类的私有方法
try {
Class<EditText> cls = EditText.class;
Method setSoftInputShownOnFocus = cls.getMethod("setShowSoftInputOnFocus", boolean.class);
setSoftInputShownOnFocus.setAccessible(true);
setSoftInputShownOnFocus.invoke(editText, false);
} catch (Exception e) {
e.printStackTrace();
}spinner弹出下拉列表后就不能在adapter中添加选项否则出现异常
1.java.lang.NoSuchMethodError: android.widget.ArrayAdapter.addAll
2.java.lang.UnsupportedOperationException
动态构造长按文本框弹出的选项
private List<String> getOptionList(EditText editText) {
List<String> optionList = new ArrayList<String>();
boolean select = false;
boolean cut = false;
boolean copy = false;
boolean paste = false;
boolean inputmethod = true;
ClipboardManager clipBoard = (ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE);
int start = editText.getSelectionStart();
int end = editText.getSelectionEnd();
cut = copy = (start != end);
paste = clipBoard.hasText();
select = (!editText.getText().toString().isEmpty());
optionList.add("");
if (select) {
optionList.add("全选");
}
if (cut) {
optionList.add("剪切");
}
if (copy) {
optionList.add("复制");
}
if (paste) {
optionList.add("粘帖");
}
if (inputmethod) {
optionList.add("输入法");
}
return optionList;
}
private String[] getOptions(EditText editText) {
List<String> optionList = getOptionList(editText);
String[] options = new String[optionList.size()];
for (int i = 0; i < options.length; i++) {
options[i] = optionList.get(i);
}
return options;
}自定义ArrayAdapter隐藏某个选项
public class CustomAdapter extends ArrayAdapter<String> {
private int hidingItemIndex;
public CustomAdapter(Context context, int textViewResourceId, String[] objects, int hidingItemIndex) {
super(context, textViewResourceId, objects);
this.hidingItemIndex = hidingItemIndex;
}
@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
View v = null;
if (position == hidingItemIndex) {
TextView tv = new TextView(getContext());
tv.setVisibility(View.GONE);
v = tv;
} else {
v = super.getDropDownView(position, null, parent);
}
return v;
}
}
private ArrayAdapter<String> getSpinnerAdapter(EditText editText) {
String[] options = getOptions(editText);
int hidingItemIndex = 0;
CustomAdapter dataAdapter = new CustomAdapter(context, android.R.layout.simple_spinner_item, options, hidingItemIndex);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
return dataAdapter;
}长按文本框弹出spinner下拉列表
final EditText editText = (EditText) view.findViewById(R.id.comment_et);
editText.setText(textView.getText());
final Spinner spinner = (Spinner) view.findViewById(R.id.spinner);
spinner.setPrompt("编辑文字");
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String text = spinner.getAdapter().getItem(position).toString();
if(!text.equals("")) {
ToastUtil.show(text);
}
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
editText.setOnLongClickListener(new OnLongClickListener() {
public boolean onLongClick(View v) {
Logger.v(TAG, "editText long click");
spinner.setAdapter(getSpinnerAdapter(editText));
spinner.performClick();
return false;
}
});PopupWindow中的EditText不支持文字编辑操作：选择文字、全选、剪切、复制、粘帖。
