Android的imeOptions =＆QUOT; actionDone＆QUOT;不工作 [英] Android imeOptions="actionDone" not working

问题描述

我想获得一个登录屏幕的Andr​​oid应用程序，到目前为止，这是我的code：

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>

当我尝试运行它，键盘显示正确的钥匙，但是当我尝试输入密码后完成preSS，没有任何反应。我用这来处理按钮preSS：

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();
            }
        }
    });

}

我知道这是一个很多code，但如果有人可以帮助我在这里将是巨大的。这是一个学校项目。

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.

推荐答案

您应该设置OnEditorActionListener为的EditText实施要执行的操作，当用户点击完成键盘。

You should set OnEditorActionListener for the EditText to implement the action you want to perform when user clicks the "Done" in keyboard.

因此​​，你需要写一些code，如：

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;
    }
});
