如何解决单击edittext时是否可能显示对话框消息?
| 我想单击一个编辑文本并显示对话框日期,所以我尝试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);
}
}
});
该对话框将显示mDatedisplay是否为按钮
但我想使用edittext
我该怎么办?
解决方法
用这个:
mDateDisplay.setClickable(true);
mDateDisplay.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showDialog(DATE_DIALOG_ID);
}
});
另外,您可以使用XML中的android:onClick
属性指向Activity子类中的点击处理函数。
(当然,这几天,当几乎每个人都使用兼容性库时,您可能希望创建并显示对话框片段,而不是调用showDialog()
,但是想法是相同的。)
, 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“ 4”之后,就像这样。
例如-android:focusableInTouchMode=\"false\"
。
因为当第一次触摸EditText时,它将调用焦点事件,而在第二次触摸时,它将调用click事件,因此您必须先禁用焦点事件。
, 对于我使用的同一件事:
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).trim());
}
};
我已经在Android的“自定义日期选择器”中编辑了代码:http://blog.codeus.net/dateslider-1-0-an-alternative-datepicker-for-android/
您可以用EditText替换Button并执行与上面的代码相同的操作。
当EditText
聚焦时,键盘似乎会弹出。为防止这种情况,请将focusable设置为false:
<EditText
...
android:focusable=\"false\"
... />
已编辑
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();
}
};
}
, 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:
<EditText
...
android:focusableInTouchMode=\"false\"
/>
因此,用户无法编辑EditText,只能单击它。
, 这是完美的代码,它将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,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 dayOfMonth) {
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;
updateDisplay();
}
};
}
, 我用ѭ14did通过以下方式完成此操作:
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\");
}
}
});
hasFocus
变量控制当前的EditText
是否具有焦点。
