Question

我是Android开发的新手，我有一个让Android EditText垂直滚动的问题。 EditText的垂直滚动对我不起作用。我关注了几个帖子和资源，但没有一个对我有用。我使用以下代码示例来启用垂直滚动功能。

this.detailsEditText.setScroller(new Scroller(this));
this.detailsEditText.setMaxLines(1);
this.detailsEditText.setVerticalScrollBarEnabled(true);
this.detailsEditText.setMovementMethod(new ScrollingMovementMethod());

以下是我在我的应用中使用的活动类和布局资源文件。

CreateAppointmentActivity.java

package lk.iit.appointmentmanagerapp.activities;

import java.sql.Date;
import java.sql.Time;

import lk.iit.appointmentmanagerapp.data.Appointment;

import android.os.Bundle;
import android.text.method.ScrollingMovementMethod;

import android.widget.Scroller;

public class CreateAppointmentActivity extends Activity {

    private EditText titleEditText; 
    private EditText timeEditText;
    private EditText detailsEditText;
    private EditText dateEditText;
    private Button saveButton;
    private Button resetButton;
    private final DatabaseHandler handler = new DatabaseHandler(this);

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_create_appointment);

        this.titleEditText = (EditText)(this.findViewById(R.id.edit_title));
        this.timeEditText = (EditText)(this.findViewById(R.id.edit_time));
        this.detailsEditText = (EditText)(this.findViewById(R.id.edit_details));
        this.dateEditText = (EditText)(this.findViewById(R.id.edit_date));

        this.detailsEditText.setScroller(new Scroller(this));
        this.detailsEditText.setMaxLines(1);
        this.detailsEditText.setVerticalScrollBarEnabled(true);
        this.detailsEditText.setMovementMethod(new ScrollingMovementMethod());

        SharedPreferences preferences = getSharedPreferences("date_variables", MODE_PRIVATE);   
        this.dateEditText.setText(preferences.getInt("Year", 0) + "-" + preferences.getInt("Month", 0) + "-" + preferences.getInt("Day", 0));
        this.dateEditText.setEnabled(false);

        this.saveButton = (Button)(this.findViewById(R.id.save_new_appointment_button));
        this.saveButton.setOnClickListener(new View.OnClickListener() {
            @SuppressWarnings("deprecation")
            @Override
            public void onClick(View v) {
                String[] dateComponents = dateEditText.getText().toString().split("-");
                String[] timeComponents = timeEditText.getText().toString().split(":");
                Appointment appointment = new Appointment();

                appointment.setAppointment_title(titleEditText.getText().toString());
                appointment.setAppointment_date(new Date(Integer.parseInt(dateComponents[0]), Integer.parseInt(dateComponents[1]), Integer.parseInt(dateComponents[2])));
                appointment.setAppointment_time(new Time(Integer.parseInt(timeComponents[0]), Integer.parseInt(timeComponents[1]), Integer.parseInt(timeComponents[2])));
                appointment.setAppointment_details(detailsEditText.getText().toString());

                boolean inserted = handler.addAppointment(appointment);
                //
                //
            }
        });
        this.resetButton = (Button)(this.findViewById(R.id.reset_button));
        this.resetButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                titleEditText.setText("");
                timeEditText.setText("");
                detailsEditText.setText("");
                dateEditText.setText("");
            }
        });
    }

}

如果我犯了任何错误，请耐心等待，因为我对这个发展领域比较陌生。如果有人帮我解决这个问题，我将不胜感激。

在java代码中尝试：

EditText dwEdit = (EditText) findViewById(R.id.DwEdit);       
dwEdit.setOnTouchListener(new OnTouchListener() {

                public boolean onTouch(View view, MotionEvent event) {
                    // TODO Auto-generated method stub
                    if (view.getId() ==R.id.DwEdit) {
                        view.getParent().requestDisallowInterceptTouchEvent(true);
                        switch (event.getAction()&MotionEvent.ACTION_MASK){
                        case MotionEvent.ACTION_UP:
                            view.getParent().requestDisallowInterceptTouchEvent(false);
                            break;
                        }
                    }
                    return false;
                }
            });

在你的xml中：

<EditText
        android:id="@+id/DwEdit"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:minLines="10"
        android:scrollbarStyle="insideInset"
        android:scrollbars="vertical" 
        android:overScrollMode="always"
        android:inputType="textCapSentences">
        </EditText>

Answer 2

如果您只想在detailEditText中滚动editText，那么您可以指定editText 50dp的高度或者您的需要，并从您的editText中删除inputType =“text”....它可以满足您的需求..

并且您不需要java相对于该editText的任何代码..
