我如何可以添加自定义按钮到AlertDialog的布局? [英] How can can I add custom buttons into an AlertDialog's layout?
问题描述
我有AlertDialog具有正负按钮。在AlertDialog布局我的EditText和两个按钮(btnAdd1,btnAdd2)。我希望当在按钮btnAdd1或btnAdd2用户点击添加相同文本的EditText在AlertDialog(但没有接近AlertDialog)。在AlertDialog这可能做或我只使用对话框?
I have AlertDialog with Positive and Negative buttons. In AlertDialog layout I have EditText and two Buttons (btnAdd1, btnAdd2). I want when user click at the Button btnAdd1 or btnAdd2 add same text to EditText in AlertDialog (but no close AlertDialog). Is this possible do in AlertDialog or I have to use only Dialog?
这是AlertDialog的布局(R.layout.prompt):
This is layout (R.layout.prompt) of AlertDialog:
<LinearLayout>
<EditText
android:id="@+id/userInput"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="text" >
<requestFocus />
</EditText>
<Button
android:id="@+id/btnAdd1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="bla" />
<Button
android:id="@+id/btnAdd2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="bla" />
</LinearLayout>
这是源$ C $ C:
And this is source code:
LayoutInflater layoutInflater = LayoutInflater.from(this);
View promptView = layoutInflater.inflate(R.layout.prompt, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
alertDialogBuilder.setView(promptView);
alertDialogBuilder
.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//...
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alertD = alertDialogBuilder.create();
alertD.show();
我想从布局获得存取权限到btnAdd1和btnAdd2。设置OnClickListener()这两个按钮。
I want get acces to the btnAdd1 and btnAdd2 from the layout. Set the OnClickListener() to these two buttons.
推荐答案
以下code会膨胀从<$ C $ C> R.layout.prompt视图并将其设置为在AlertDialog。在正
和负
按钮将不会被使用。您可以设置的onClick
行为的 btnAdd1
和 btnAdd2
:
The following code will inflate a view from R.layout.prompt
and set it to the AlertDialog. The positive
and negative
buttons will not be used. You can set the onClick
behaviors for btnAdd1
and btnAdd2
:
LayoutInflater layoutInflater = LayoutInflater.from(this);
View promptView = layoutInflater.inflate(R.layout.prompt, null);
final AlertDialog alertD = new AlertDialog.Builder(this).create();
EditText userInput = (EditText) promptView.findViewById(R.id.userInput);
Button btnAdd1 = (Button) promptView.findViewById(R.id.btnAdd1);
Button btnAdd2 = (Button) promptView.findViewById(R.id.btnAdd2);
btnAdd1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// btnAdd1 has been clicked
}
});
btnAdd2.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// btnAdd2 has been clicked
}
});
alertD.setView(promptView);
alertD.show();
