Android Edit text onclicklistener 在第一次点击时不起作用

Question

我使用 onClick 编写函数方法 EditText , 将数据加载到 RecycleView .点击时EditText将所有数据加载到 AlertBox如果单击一个。然后将所有数据加载到RecycleView根据它。第一次不显示，但我再次单击 EditText并从 AlertBox 中选择数据然后在 RecycleView 中显示详细信息

activity_day_plan.xml

<EditText
        android:id="@+id/txtline"
        android:layout_width="156dp"
        android:layout_height="33dp"
        android:clickable="true"
        android:focusable="false"
        android:focusableInTouchMode="false"

        android:layout_marginEnd="8dp"
        android:layout_marginStart="8dp"
        android:layout_marginTop="12dp"
        android:background="@drawable/input"
        android:ems="10"
        android:inputType="textPersonName"
        android:textAlignment="center"
        app:layout_constraintEnd_toStartOf="@+id/btnview"
        app:layout_constraintStart_toEndOf="@+id/txtfactoryname"
        app:layout_constraintTop_toBottomOf="@+id/txtfac" />

Main Activity

private EditText addline;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_day_plan);

    addline=(EditText)findViewById(R.id.txtline);

    addline.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            getlist();
        }

public void getlist()

                            for (int i = 0; i < jsonArray.length(); i++) {
                                JSONObject jsonObject = jsonArray.getJSONObject(i);
                                String hourcode1 = jsonObject.getString("hour_code");

                            recyclerView.setAdapter(adapter);
                            loadingbar.dismiss();

        stringRequest.setRetryPolicy(new DefaultRetryPolicy(
                60000,
                DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
                DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
        MySingleton.getInstance(getApplicationContext()).addToRequestque(stringRequest);
    }
}

使用onTouchListener而不是 onClickListener

addline.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_UP) {
            getlist();
            return true;
        }
        return false;
    }
});
