第一次单击时，Android Edit文本onclicklistener无效

Question

我写了使用onClick方法来将EditText数据加载到的函数RecycleView。单击时，将EditText所有数据加载到AlertBox，如果单击一个。然后RecycleView根据它加载所有数据。第一次没有显示，但是我再次单击EditText并选择数据，AlertBox然后在RecycleView

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" />

主要活动

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()
{
    arrayList.clear();
    if(addfac.getText().equals(""))
    {
        Toast.makeText(DayPlanActivity.this,"Please Select Factory Code",Toast.LENGTH_SHORT).show();
    }
    else if(addline.getText().equals(""))
    {
        Toast.makeText(DayPlanActivity.this,"Please Select Line Code",Toast.LENGTH_SHORT).show();
    }
    else {
        loadingbar.setMessage("Loading All Line Details");
        StringRequest stringRequest = new StringRequest(Request.Method.POST, Constants.GETDALYDETAILS_URL,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        try {
                            JSONArray jsonArray = new JSONArray(response);
                            for (int i = 0; i < jsonArray.length(); i++) {
                                JSONObject jsonObject = jsonArray.getJSONObject(i);
                                String hourcode1 = jsonObject.getString("hour_code");
                                String prodqty = jsonObject.getString("qrytime");
                                String datetime = jsonObject.getString("hourqty");

                                arrayList.add(gethour);
                            }
                            adapter = new ContactAdapter(arrayList);
                            recyclerView.setAdapter(adapter);
                            loadingbar.dismiss();
                        } catch (JSONException e) {

        stringRequest.setRetryPolicy(new DefaultRetryPolicy(

        MySingleton.getInstance(getApplicationContext()).addToRequestque(stringRequest);
    }
}

Answer 1

您需要做的就是禁用focus该视图，您的视图将对第一次单击做出反应。

在 XML 中

<androidx.appcompat.widget.AppCompatEditText
        android:id="@+id/edit_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:focusable="false" <!--this line does the magic -->
        android:gravity="top" />

爪哇语

    EditText editText = findViewById(R.id.username);
    editText.setFocusable(false);

在科特林中

    val editText = findViewById<EditText>(R.id.edit_text)
    editText.isFocusable = false

Answer 2

使用onTouchListener代替onClickListener

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

Answer 3

使用onFocusChangeListener而不是onClickListener：

yourEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
       @Override
       public void onFocusChange(View view, boolean b) {
             if (b)
                // do your stuff here if b is true
       }
});
