我有一个包含 3 个 EditText 的对话框,用于获取 ftp 地址、用户名和密码.我使用 .setNeutralButton 创建了一个测试连接"按钮.我让它连接到 ftp 并显示一个带有结果的 Toast,但我不希望测试按钮关闭对话框.如何在连接测试期间保持对话框打开?
I have a Dialog with 3 EditTexts that I use to get an ftp address, username, and password. I used .setNeutralButton to create a button to "Test Connection". I got it working to connect to the ftp and show a Toast with the result but I don't want the Test Button to close the Dialog. How can I keep the Dialog open during the connection test?
livePreviewChk.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
LinearLayout lila1 = new LinearLayout(NewSite.this);
lila1.setOrientation(1); // 1 is for vertical orientation
final EditText serverName = new EditText(NewSite.this);
serverName.setHint("Server name");
final EditText serverAddress = new EditText(NewSite.this);
serverAddress.setHint("Server Address");
final EditText username = new EditText(NewSite.this);
username.setHint("Username:");
final EditText password = new EditText(NewSite.this);
password.setHint("Password");
AlertDialog.Builder alt_bld = new AlertDialog.Builder(
NewSite.this);
alt_bld.setIcon(R.drawable.ftpicon);
alt_bld.setTitle("Enter the login details for the host FTP")
.setCancelable(true)
.setPositiveButton("Save",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
}
}
})
.setNeutralButton("Test Connection",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
FTPConnector testConnection = new FTPConnector();
boolean status = testConnection
.ftpConnect(host, user, pass,
port);
if (status == true) {
connectionSuccessfull = true;
} else {
connectionSuccessfull = false;
}
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
// if this button is clicked, just close
// the dialog box and do nothing
dialog.cancel();
}
});
lila1.addView(serverName);
lila1.addView(serverAddress);
lila1.addView(username);
lila1.addView(password);
AlertDialog alert = alt_bld.create();
alert.setView(lila1);
alert.show();
}
});
据我所知,不扩展 Dialog
类是不可能的.但是,使用您拥有的功能,将其放在自己的 Activity
中并使用 Dialog 主题
可能会更容易和更好.您所要做的就是为此将您的代码放入一个新的 Activity
中,并在您的 manifest
中使用 dialog 主题
From what I know, it is not possible without extending the Dialog
class. However, with the functionality that you have it may be easier and better just to put it in its own Activity
and use a Dialog theme
. All you have to do is put your code into a new Activity
for this and in your manifest
use the dialog theme
<activity
android:name="com.your.package.YourClassName"
android:label="YOurLabel"
android:theme="@android:style/Theme.Dialog" >
</activity>
这将提供 Dialog
的外观和感觉,同时包含在它自己的 Activity
This will give the look and feel of a Dialog
while being contained in its own Activity
这是一个 关于扩展对话框的答案.我还没有看透这一切,但看起来如果你选择这个选项,它可能会给你你需要的东西.
Here is a SO answer on extending Dialog. I haven't looked through it all but looks like it may give you what you need if you choose this option.
