EditText On A Popup Window
提问by Laura
I am developing on Android 2.2 using Java. I put an editText on a PopupWindow and it's not working. It acts like a disabled edit text, clicking on the edit text won't show the soft keyboard. How can I add an edit text on a popupWindow?
我正在使用 Java 在 Android 2.2 上进行开发。我在 PopupWindow 上放置了一个 editText 但它不起作用。它就像一个禁用的编辑文本，点击编辑文本不会显示软键盘。如何在弹出窗口上添加编辑文本？

I have resolved the problem like this: I put the popupWindow.setFocusable(true);and now it's working. It seems that the edit text which was on a pop window didn't have focus because the popup window didn't have focus.
我已经解决了这样的问题：我把popupWindow.setFocusable(true);它现在工作了。似乎弹出窗口上的编辑文本没有焦点，因为弹出窗口没有焦点。

Does the EditText definitely have the android:editable property set to true? If it's false it will be disabled as you describe.
EditText 是否肯定将 android:editable 属性设置为 true？如果它是假的，它将按照您的描述被禁用。

Just try:
你试一试：
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Title");
alert.setMessage("Message");
// Set an EditText view to get user input
final EditText input = new EditText(this);
alert.setView(input);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Do something with value!
}
});
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Canceled.
}
});
alert.show();

call this code from any listener
从任何侦听器调用此代码
private void popUpEditText() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Comments");
final EditText input = new EditText(this);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.MATCH_PARENT);
input.setLayoutParams(lp);
builder.setView(input);
// Set up the buttons
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// do something here on OK
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
builder.show();
}
