Android EditText onClickListener

2019-01-13 11:53发布

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

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).

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" />

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).

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.

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.

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);
   }
 }
};
