Android 单次点击时未显示日期选择器对话框

期望值：

public static void hideKeyboard(Activity activity) {
    InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
    View view = activity.getCurrentFocus();
    if (view == null) {
        view = new View(activity);
    }

    if (imm != null)
        imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

当用户点击MaterialTextView组件时，DatePickerDialog应该打开

发生了什么事：

public static void hideKeyboard(Activity activity) {
    InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
    View view = activity.getCurrentFocus();
    if (view == null) {
        view = new View(activity);
    }

    if (imm != null)
        imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

<com.google.android.material.textview.MaterialTextView
                        android:id="@+id/edIssueDate"
                        android:layout_width="match_parent"

用户需要在MaterialTextView组件上点击两次以打开DatePickerDialog

main活动

protected void onCreate(Bundle SavedInstanceState){
MaterialTextView issueDate = findViewById(R.id.edIssueDate);
 issueDate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            final Calendar c = Calendar.getInstance();
            int year = c.get(Calendar.YEAR);
            int month = c.get(Calendar.MONTH);
            int day = c.get(Calendar.DAY_OF_MONTH);

            hideKeyboard(AddNewCoupon.this);
            DatePickerDialog datePickerDialog = new DatePickerDialog(AddNewCoupon.this, new DatePickerDialog.OnDateSetListener() {
                @Override
                public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                    issueDate.setText(String.valueOf(dayOfMonth)+"/"+String.valueOf(month)+"/"+String.valueOf(year));
                    //newCustomer.hideKeyboard(AddNewCoupon.this);
                }
            }, year, month, day);
            datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
            datePickerDialog.show();
        }
    });
}

hideKeyboard（）方法：

public static void hideKeyboard(Activity activity) {
    InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
    View view = activity.getCurrentFocus();
    if (view == null) {
        view = new View(activity);
    }

    if (imm != null)
        imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

<com.google.android.material.textview.MaterialTextView
                        android:id="@+id/edIssueDate"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:layout_marginTop="4dp"
                        android:ems="10"
                        android:focusable="auto"
                        android:focusableInTouchMode="true"
                        android:hint="@string/txtVIssueingDtHint"
                        android:nextFocusDown="@id/edExpDate"
                        android:onClick="showDatePickerDialogForIssue"
                        android:paddingLeft="4dp"
                        android:textColor="@color/design_default_color_on_secondary"
                        android:textSize="18sp"
                        app:layout_constraintEnd_toEndOf="parent"
                        app:layout_constraintStart_toStartOf="parent"
                        app:layout_constraintTop_toBottomOf="@+id/textView2" />

    View view = activity.getCurrentFocus();
    if (view == null) {

    }

    if (imm != null)
        imm.hideSoftInputFromWindow(view.getWindowToken(), 0);

代码在DatePickerDialog打开时运行良好，但问题是用户需要点击两次才能对其进行操作。我犯了什么错误？如何修复代码

将focusable和focusableInTouchMode的值更改为false，这样就可以了

 android:focusable="false"
 android:focusableInTouchMode="false"

希望这会有帮助

将您的文本视图更改为

<com.google.android.material.textview.MaterialTextView
                        android:id="@+id/edIssueDate"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:layout_marginTop="4dp"
                        android:ems="10"
                        android:hint="@string/txtVIssueingDtHint"
                        android:onClick="showDatePickerDialogForIssue"
                        android:paddingLeft="4dp"
                        android:textColor="@color/design_default_color_on_secondary"
                        android:textSize="18sp"
                        app:layout_constraintEnd_toEndOf="parent"
                        app:layout_constraintStart_toStartOf="parent"
                        app:layout_constraintTop_toBottomOf="@+id/textView2" />

删除此选项，除非它是必需的选项

android:focusable="auto"
android:focusableInTouchMode="true"

移动

hideKeyboard（AddNewCoupon.this）到块的末尾，即
datePickerDialog.show（）之后，我认为您的问题与焦点转移问题有关。我运行了您的代码，一次单击就打开了对话框，因此问题可能与您尚未共享的代码有关。仅供参考，android:onClick=“showDatePickerDialogForIssue”
是多余的，因为您实现了setonclicklistener您的解决方案对我来说很有效。现在我还有一个问题。当用户单击“下一步”按钮时，控件将跳过此组件，直接转到DatePicker旁边的组件，这是一个糟糕的用户体验，如何管理焦点转移。我如何管理焦点转移？
