I am simply trying to have an onlick listen on an Edit text inside a TextInputLayout. It works but I need to click on the EditText twice for it to trigger I dont understand why. Here is my code:

xml:

  <android.support.design.widget.TextInputLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp">

        <EditText
            android:id="@+id/start_date"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:ems="10"
            android:hint="Starting Date*: "
            android:inputType="textPersonName" />
    </android.support.design.widget.TextInputLayout>

听众:

   private void setListenners() {
        EditText startDate = (EditText) mView.findViewById(R.id.start_date);
        startDate.setOnClickListener(new View.OnClickListener() {
            @RequiresApi(api = Build.VERSION_CODES.N)
            @Override
            public void onClick(View v) {
                Calendar mcurrentDate=Calendar.getInstance();
                int mYear = mcurrentDate.get(Calendar.YEAR);
                int mMonth = mcurrentDate.get(Calendar.MONTH);
                int mDay = mcurrentDate.get(Calendar.DAY_OF_MONTH);

                DatePickerDialog mDatePicker=new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker datePicker, int year, int month, int day) {
                        Log.d("DEBUG", "year: " + year + " month: " + month + " day: " + day);
                    }
                },mYear, mMonth, mDay);
                mDatePicker.show();
            }
        });
    }

推荐答案

将属性 android:focusableInTouchMode 设置为 false

android:focusableInTouchMode="false"

在您的edittext xml代码中.

in your edittext xml code.

根据文档的说明， android:focusableInTouchMode 是:

Explanation, as from docs, android:focusableInTouchMode is:

布尔值，控制视图在触摸时是否可以聚焦 模式.如果对于某个视图而言这是正确的，则该视图可以在以下情况下获得焦点 单击，如果单击另一个视图，则可以保持焦点 没有将此属性设置为true.

Boolean that controls whether a view can take focus while in touch mode. If this is true for a view, that view can gain focus when clicked on, and can keep focus if another view is clicked on that doesn't have this attribute set to true.

，EditText默认为 true .

换句话说:第一次单击将使edittext获得焦点，而第二次单击将触发ClickListener.因此，您应该禁用对触摸的关注.

In other words: the first click will make the edittext to gain focus and second click is the one that triggers the ClickListener. So you should disable gaining focus on touch.
