为什么要双击以显示日期对话框

Question

为什么当我有两个编辑文本框时 - （一个调用日期对话框，另一个调用时间对话框）。 为什么我必须按两次才能打开对话框。 第一次按聚焦它，然后第二次按打开对话框。

我如何使当我按下编辑文本框时，对话框在第一次按下时打开

Java编码

public class MainActivity extends Activity {
int hour = -1, min = -1;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    // ////TIME picker
    EditText etOne = (EditText) findViewById(R.id.editText1);
    etOne.setOnClickListener(new EditText.OnClickListener() {

                min = c.get(Calendar.MINUTE);
            }
            showTimeDialog(v, hour, min);

XML编码

<?xml version="1.0" encoding="utf-8"?>

<EditText
    android:id="@+id/editText1"
    android:layout_width="300dp"
    android:layout_height="30dp"
    android:layout_gravity="left"
    android:background="#999999"
    android:gravity="left" />
<EditText
    android:id="@+id/editText2"
    android:layout_width="300dp"
    android:layout_height="30dp"
    android:layout_gravity="left"
    android:background="#998899"
    android:gravity="left" />

Answer 1

将其用于编辑文本

android:focusable="false"

Answer 2

与其使用

OnClickListener，不如在这里使用 OnFocusChangeListener。

例如：

etOne.setOnFocusChangeListener(new OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if(hasFocus){
            //show whatever you want
        }
    }
});

Answer 3

试试看

 You can use OnClickListener event to handle the dialog box but after disabling the            android:focusableInTouchMode of EditText in the xml file like this. eg -      
 android:focusableInTouchMode="false".
     Because when the EditText is first touched it calls the focus event and on second touch it call the click event so you have to disable the focus event first.
