Android EditText onClickListener

问题:

i want an EditText which creates a DatePicker when is pressed. So i write the next code:

    mEditInit = (EditText) findViewById(R.id.date_init);
    mEditInit.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showDialog(DATEINIT_DIALOG);
        }

    });

But when i press the EditText the action is the typical: a cursor waiting for typing text instead show the Dialog i want.

Any idea?

Thanks

The keyboard seems to pop up when the EditText gains focus. To prevent this, set focusable to false:

<EditText
    ...
    android:focusable="false"
    ... />

This behavior can vary on different manufacturers' Android OS flavors, but on the devices I've tested I have found this to to be sufficient. If the keyboard still pops up, using hints instead of text seems to help as well:

myEditText.setText("My text");    // instead of this...
myEditText.setHint("My text");    // try this

Once you've done this, your on click listener should work as desired:

myEditText.setOnClickListener(new OnClickListener() {...});

Normally, you want maximum compatibility with EditText's normal behaviour.

So you should not use android:focusable="false" as, yes, the view will just not be focusable anymore which looks bad. The background drawable will not show its "pressed" state anymore, for example.

What you should do instead is the following:

myEditText.setInputType(InputType.TYPE_NULL);
myEditText.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // showMyDialog();
    }
});
myEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (hasFocus) {
            // showMyDialog();
        }
    }
});

By setting the input type to TYPE_NULL, you prevent the software keyboard from popping up.

By setting the OnClickListener and OnFocusChangeListener, you make sure that your dialog will always open when the user clicks into the EditText field, both when it gains focus (first click) and on subsequent clicks.

Just setting android:inputType="none" or setInputType(InputType.TYPE_NULL) is not always enough. For some devices, you should set android:editable="false" in XML as well, although it is deprecated. If it does not work anymore, it will just be ignored (as all XML attributes that are not supported).

I had this same problem. The code is fine but make sure you change the focusable value of the EditText to false.

<EditText
android:id="@+id/date"
android:focusable="false"/>

I hope this helps anyone who has had a similar problem!

Here is the solution I implemented

mPickDate.setOnKeyListener(new View.OnKeyListener() {

    @Override
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        showDialog(DATE_DIALOG_ID);
        return false;
    }
});

OR

mPickDate.setOnFocusChangeListener(new View.OnFocusChangeListener() {

    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        showDialog(DATE_DIALOG_ID);

    }
});

See the differences by yourself. Problem is since (like RickNotFred said) TextView to display the date & edit via the DatePicker. TextEdit is not used for its primary purpose. If you want the DatePicker to re-pop up, you need to input delete (1st case) or de focus (2nd case).

Default working of EditText: On first click it focuses and on second click it handles onClickListener so you need to disable focus. Then on first click the onClickListener will handle.

To do that you need to add this android:focusableInTouchMode="false" attribute to your EditText. That's it!

Something like this:

    <EditText
        android:id="@+id/editText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:focusableInTouchMode="false"
        android:inputType="text" />

IMHO I disagree with RickNotFred's statement:

Popping a dialog when an EditText gets focus seems like a non-standard interface.

Displaying a dialog to edit the date when the use presses the an EditText is very similar to the default, which is to display a keyboard or a numeric key pad. The fact that the date is displayed with the EditText signals to the user that the date may be changed. Displaying the date as a non-editable TextView signals to the user that the date may not be changed.

The following works perfectly for me.

First set your date picker widget's input to 'none' to prevent the soft keyboard from popping up:

<EditText android:inputType="none" ... ></EditText>

Then add these event listeners to show the dialog containing the date picker:

// Date picker
EditText dateEdit = (EditText) findViewById(R.id.date);
dateOfBirthEdit.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) {
            showDialog(DIALOG_DATE_PICKER);
        }
        return false;
    }
});

dateEdit.setOnFocusChangeListener(new OnFocusChangeListener() {

    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (hasFocus) {
            showDialog(DIALOG_DATE_PICKER);
        } else {
            dismissDialog(DIALOG_DATE_PICKER);
        }
    }
});

One last thing. To make sure typed days, months, or years are correctly copied from the date picker, call datePicker.clearFocus() before retrieving the values, for instance via getMonth().

Nice topic. Well, I have done so. In XML file:

<EditText
    ...
    android:editable="false"
    android:inputType="none" />

In Java-code:

txtDay.setOnClickListener(onOnClickEvent);
txtDay.setOnFocusChangeListener(onFocusChangeEvent);

private View.OnClickListener onOnClickEvent = new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        dpDialog.show();
    }
};
private View.OnFocusChangeListener onFocusChangeEvent = new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (hasFocus)
            dpDialog.show();
    }
};

Here is what worked for me

Set editable to false

<EditText android:id="@+id/dob"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="Date of Birth"
android:inputType="none"
android:editable="false"

/>

Then add an event listener for OnFocusChange

private  View.OnFocusChangeListener onFocusChangeDOB= new View.OnFocusChangeListener() {

@Override
 public void onFocusChange(View v, boolean hasFocus) {
   if (hasFocus){
     showDialog(DATE_DIALOG_ID);
   }
 }
};

This Works For me:

mEditInit = (EditText) findViewById(R.id.date_init);
mEditInit.setKeyListener(null);
mEditInit.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if(hasFocus)
            {
                mEditInit.callOnClick();
            }
        }
    });
mEditInit.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        showDialog(DATEINIT_DIALOG);
    }

});

回答11:

As Dillon Kearns suggested, setting focusable to false works fine. But if your goal is to cancel the keyboard when EditText is clicked, you might want to use:

mEditText.setInputType(0);

回答12:

Why did not anyone mention setOnTouchListener? Using setOnTouchListener is easy and all right, and just return true if the listener has consumed the event, false otherwise.
