制作android EditText垂直滚动条

我是Android开发新手，我有一个使得Android EditText垂直滚动的问题。 EditText的垂直滚动对我不起作用。我跟着几个帖子和资源，但他们都没有为我工作。我正在使用以下代码示例启用垂直滚动功能。制作android EditText垂直滚动条

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

以下是分别在我的应用程序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.widget.EditText; 
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(""); 
      } 
     }); 
    }

你需要滚动所有的EditText？ – 2015-04-03 06:25:00

是的，我需要将EditText中的文本垂直向上和向下滚动，并只显示EditText的一行。 – 2015-04-03 06:34:31

在Java代码中试试这个：

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; 
       } 
      });

而在你的xml：

<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>

对不起，但这不起作用，你只能水平滚动，不会发生垂直滚动。请注意，我正在使用目标为Android 5.0.1的AVD，这是否与它有关？ – 2015-04-03 06:22:39

问题是什么？此代码正在我的nexus设备中工作。那是5.1。告诉我这个问题。我尽力帮助你 – Amsheer 2015-04-03 07:14:03

如果你想只在detailEditText滚动EDITTEXT那么你指定高度EDITTEXT 50dp或您的需要和删除的inputType =“text”from your editText ....它满足您的需求..

并且您不需要任何Java代码相对于该editText ..
