问题
I am trying to get a login screen for an Android app and so far this is my code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:id="@+id/linearLayout1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:orientation="vertical">
<EditText
android:id="@+id/username"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Username"
android:inputType="text"
android:singleLine="true"
android:imeOptions="actionNext">
<requestFocus />
</EditText>
<EditText
android:id="@+id/password"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Password"
android:inputType="textPassword"
android:singleLine="true"
android:imeOptions="actionDone" />
<Button
android:id="@+id/buttonLaunchTriage"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="@string/login" />
</LinearLayout>
</RelativeLayout>
When I try to run it, the keyboard shows the right keys but when I try to press done after entering the password, nothing happens. I am using this to handle the button press:
private void setupLoginButton() {
Button launchButton = (Button) findViewById(R.id.buttonLaunchTriage);
launchButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
EditText username = (EditText) findViewById(R.id.patient_start_userName_value);
EditText password = (EditText) findViewById(R.id.patient_start_password_value);
try {
if(TriageApplicationMain.validateUser(username.getText().toString(),password.getText().toString(),getApplicationContext()))
{
Toast.makeText(StartActivity.this,
"Launching Triage Application", Toast.LENGTH_SHORT)
.show();
startActivity(new Intent(StartActivity.this, MainActivity.class));
}
else
{
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
StartActivity.this);
// set dialog message
alertDialogBuilder
.setMessage("Incorrect Credentials")
.setCancelable(false)
.setPositiveButton("OK",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
// if this button is clicked, close
// current activity
dialog.cancel();
}
});
// create alert dialog
AlertDialog alertDialog = alertDialogBuilder.create();
// show it
alertDialog.show();
}
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
I know this is a lot of code, but if anyone could help me here it would be great. This is for a school project.
PS: I have searched through Google for a solid hour before posting this so please don't criticize for not doing that. If you find a link that is useful then please share.
回答1:
Just add android:inputType="..."
to your EditText. It will work!! :)
回答2:
You should set OnEditorActionListener for the EditText to implement the action you want to perform when user clicks the "Done" in keyboard.
Thus, you need to write some code like:
password.setOnEditorActionListener(new OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE) {
// Do whatever you want here
return true;
}
return false;
}
});
See the tutorial at android developer site

Qianqian is correct. Your code only listens for the button click event, not for the EditorAction event.
I want to add that some phone vendors may not properly implement the DONE action. I have tested this with a Lenovo A889 for example, and that phone never sends EditorInfo.IME_ACTION_DONE
when you press done, it always sends EditorInfo.IME_ACTION_UNSPECIFIED
so I actually end up with something like
myEditText.setOnEditorActionListener(new EditText.OnEditorActionListener() {
@Override
public boolean onEditorAction(final TextView v, final int actionId, final KeyEvent event)
{
boolean handled=false;
// Some phones disregard the IME setting option in the xml, instead
// they send IME_ACTION_UNSPECIFIED so we need to catch that
if(EditorInfo.IME_ACTION_DONE==actionId || EditorInfo.IME_ACTION_UNSPECIFIED==actionId)
{
// do things here
handled=true;
}
return handled;
}
});
Also note the "handled" flag (Qianqian didn't explain that part). It might be that other OnEditorActionListeners higher up are listening for events of a different type. If your method returns false, that means you didn't handle this event and it will be passed on to others. If you return true that means you handled/consumed it and it will not be passed on to others.

Use android:inputType="Yours"
then
android:lines="1"
android:imeOptions="actionDone"
回答5:
After trying many things, this is what worked for me:
android:maxLines="1"
android:inputType="text"
android:imeOptions="actionDone"
回答6:
You should set OnEditorActionListener for the EditText to implement the action you want to perform when user clicks the "Done" in keyboard.
回答7:
just Add this to your attributes :
android:inputType="textPassword"
