是否有可能在单击edittext时显示对话框消息?

我想点击一个edittext并显示对话日期,所以我试试

mDateDisplay = (EditText) findViewById(R.id.dateDisplay); mDateDisplay.setOnFocusChangeListener(new View.OnFocusChangeListener() { @Override public void onFocusChange(View v, boolean hasFocus) { if (hasFocus) { showDialog(DATE_DIALOG_ID); } } }); 

对话框将显示mDateDisplay是否为按钮

但我想使用edittext

我该怎么办?

用这个:

 mDateDisplay.setClickable(true); mDateDisplay.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { showDialog(DATE_DIALOG_ID); } }); 

或者,您可以使用XML中的android:onClick属性指向Activity子类中的单击处理函数。

(当然,当然,当几乎每个人都使用兼容性库时,你可能想要创建并显示一个对话框片段而不是调用showDialog() ,但这个想法是一样的。)

您可以使用OnClickListener事件来处理对话框,但是在禁用xml文件中的EditText的android:focusableInTouchMode focusableInTouchMode之后。 例如 – android:focusableInTouchMode="false"

因为首次触摸EditText时,它会调用焦点事件,第二次触摸时会调用click事件,因此您必须先禁用焦点事件。

对于我使用的相同的事情:

  sel_date.setClickable(true); sel_date.setOnClickListener(new OnClickListener(){ @Override public void onClick(View arg0) { // TODO Auto-generated method stub showDialog(DEFAULTDATESELECTOR_ID); } }); 

并将选定日期设置为EditText的值:

 private DateSlider.OnDateSetListener mDateSetListener = new DateSlider.OnDateSetListener() { public void onDateSet(DateSlider view, Calendar selectedDate) { // update the dateText view with the corresponding date sel_date.setText(String.format("%te-%tB-%tY", selectedDate, selectedDate, selectedDate).trim()); } }; 

我在Android中编辑了自定义日期选择器中的代码: http : //blog.codeus.net/dateslider-1-0-an-alternative-datepicker-for-android/

您可以使用EditText替换Button,并执行与上述代码相同的操作。

EditText获得焦点时,键盘似乎会popup。 要防止这种情况,请将focusable设置为false:

检查以下代码:

 public class Main extends Activity { EditText et1,et2; static final int DATE_DIALOG_ID = 0; static final int DATE_DIALOG_ID1 = 1; private int mYear; private int mMonth; private int mDay; private int mYear1; private int mMonth1; private int mDay1; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); et1=(EditText)findViewById(R.id.EditText01); et2=(EditText)findViewById(R.id.EditText02); final Calendar c = Calendar.getInstance(); mYear = c.get(Calendar.YEAR); mMonth = c.get(Calendar.MONTH); mDay = c.get(Calendar.DAY_OF_MONTH); et1.setText("month/year"); et2.setText("month/year"); et1.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { // TODO Auto-generated method stub showDialog(DATE_DIALOG_ID); return false; } }); et2.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { // TODO Auto-generated method stub showDialog(DATE_DIALOG_ID1); return false; } }); } @Override protected Dialog onCreateDialog(int id) { switch (id) { case DATE_DIALOG_ID: return new DatePickerDialog(this, mDateSetListener, mYear, mMonth, mDay); case DATE_DIALOG_ID1: return new DatePickerDialog(this, mDateSetListener1, mYear1, mMonth1, mDay1); } return null; } // updates the date in the TextView private void updateDisplay() { et1.setText(new StringBuilder() // Month is 0 based so add 1 .append(mMonth + 1).append("-").append(mYear)); } private void updateDisplay1() { et2.setText(new StringBuilder() // Month is 0 based so add 1 .append(mMonth1 + 1).append("-").append(mYear1)); } // the callback received when the user "sets" the date in the dialog private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() { @Override public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { // TODO Auto-generated method stub mYear = year; mMonth = monthOfYear; mDay = dayOfMonth; updateDisplay(); } }; private DatePickerDialog.OnDateSetListener mDateSetListener1 = new DatePickerDialog.OnDateSetListener() { @Override public void onDateSet(DatePicker view, int year1, int monthOfYear1, int dayOfMonth1) { // TODO Auto-generated method stub mYear1 = year1; mMonth1 = monthOfYear1; mDay1 = dayOfMonth1; updateDisplay1(); } }; } 

这是一个完美的代码,可以为您提供所需的输出:

 public class TextView_Calendar extends Activity { EditText et1,et2; static final int DATE_DIALOG_ID = 0; private int mYear; private int mMonth; private int mDay; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); et1=(EditText)findViewById(R.id.et1); final Calendar c = Calendar.getInstance(); mYear = c.get(Calendar.YEAR); mMonth = c.get(Calendar.MONTH); mDay = c.get(Calendar.DAY_OF_MONTH); et1.setText("month/year"); et1.setOnTouchListener(new OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { showDialog(DATE_DIALOG_ID); return false; } }); } @Override protected Dialog onCreateDialog(int id) { switch (id) { case DATE_DIALOG_ID: return new DatePickerDialog(this, mDateSetListener, mYear, mMonth, mDay); } return null; } // updates the date in the TextView private void updateDisplay() { et1.setText(new StringBuilder() // Month is 0 based so add 1 .append(mDay).append("-").append(mMonth + 1).append("-").append(mYear)); } // the callback received when the user "sets" the date in the dialog private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() { public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { mYear = year; mMonth = monthOfYear; mDay = dayOfMonth; updateDisplay(); } }; } 

我遇到了类似的问题。 简单来说,为了解决这个问题,我使用了以下代码:

 editText.setClickable(true); editText.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // showDialog } }); 

在XML中:

  

因此,用户无法编辑EditText,只能单击它。

我通过以下方式使用onFocusChangeListener完成它:

mCompleteByEditText =(EditText)findViewById(R.id.completion); mCompleteByEditText .setOnFocusChangeListener(new OnFocusChangeListener(){

  @Override public void onFocusChange(View v, boolean hasFocus) { if (hasFocus) { DialogFragment newFragment = new TimePickerFragment(); newFragment.show(getSupportFragmentManager(), "timePicker"); } } }); 

hasFocusvariables控制当前EditText是否具有焦点。
