很抱歉打扰你们,但我一直在扼杀这个工作。
我想要它做什么:
EditText显示提示。
用户点击EditText,打开微调器并选择他们的性别。然后变成一个字符串并放入EditText(性别)
它实际上在做什么: “男性”我的微调器中的第一个元素已经放入我的EditText中,然后用户甚至点击它。(我从未看到我的提示:“性别”)....当我尝试时,微调器根本不会打开点击EditText(性别)
发生了什么事?
我的代码:
private Spinner sexSpinner;
String[] arrayForSpinner = {"Male", "Female"};
//Inside OnCreate method:
sexSpinner = (Spinner)findViewById(R.id.spinner);
adapter = new ArrayAdapter<String>(this, R.layout.spinner_row, arrayForSpinner);
sexSpinner.setAdapter(adapter);
sexSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view,int position, long id) {
gender.setText(sexSpinner.getSelectedItem().toString());
}
gender.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View arg0, boolean hasFocus) {
// TODO Auto-generated method stub
if(hasFocus){
sexSpinner.performClick();
}
}
});
布局:
<EditText
android:layout_width="75dp"
android:layout_height="wrap_content"
android:layout_marginBottom="12dp"
android:focusable="false"
android:longClickable="false"
android:clickable="true"
android:inputType="date"
android:maxLines="1"
android:singleLine="true"
android:hint="Gender"
android:textColorHint="@color/white"
android:textColor="@color/white"
android:ems="10"
android:id="@+id/signup_input_gender"
android:layout_below="@+id/signup_input_birthday"
android:layout_centerHorizontal="true"
android:backgroundTint="@android:color/white"/>
<Spinner
android:background="@color/Blue"
android:id="@+id/spinner"
android:paddingLeft="0dp"
android:layout_width="75dp"
android:layout_height="40dp"
android:layout_marginRight="40dp"
android:layout_marginBottom="6dp"
android:layout_below="@+id/linearlayout"
android:visibility="invisible" />

在此,我将展示如何使用AutoCompleteTextView
。此外,由于我正在复制项目中的所有代码,因此我还添加了Imageview
(删除按钮),用于重置AutoCompleteTextView
。
首先是XML代码(使用ConstraintLayout
):
<AutoCompleteTextView
android:layout_width="200dp"
android:layout_height="30dp"
android:hint="Select Gender"
android:id="@+id/acT1"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:background="#ffffff"
android:textAlignment="center"
android:dropDownHeight="155dp"
android:cursorVisible="false"
android:maxLines="1"
android:focusable="false"
android:clickable="true"
android:inputType="none"
/>
<ImageView
android:src="@drawable/clear"
android:layout_width="wrap_content"
android:layout_height="20dp"
app:layout_constraintRight_toRightOf="@+id/acT1"
app:layout_constraintBottom_toBottomOf="@+id/acT1"
app:layout_constraintTop_toTopOf="@+id/acT1"
android:alpha=".2"
android:id="@+id/delButton"
android:contentDescription="Delete Button" />
现在的Java代码:
AutoCompleteTextView acTV1 = findViewById(R.id.acT1);
ImageView delButton = findViewById(R.id.delButton);
final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<>(
this, android.R.layout.simple_list_item_1, getResources()
.getStringArray(R.array.Gender_Names));
String selection;
acTV1.setAdapter(arrayAdapter);
acTV1.setCursorVisible(false);
acTV1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
acTV1.showDropDown();
selection = (String) parent.getItemAtPosition(position);
Toast.makeText(getApplicationContext(), selection,
Toast.LENGTH_SHORT);
delButton.setAlpha(.8f);
}
});
acTV1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(final View arg0) {
acTV1.showDropDown();
}
});
delButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
acTV1.setText(null);
delButton.setAlpha(.2f);
selection = null;
}
});
和Gender_Names数组,在strings.xml中定义:
<string-array name="Gender_Names">
<item>Male</item>
<item>Female</item>
<item>Other</item>
</string-array>
它的外观如下:

要显示Spinner
(使用gender.setOnClickListener()),
gender.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
flag = true;
sexSpinner.performClick();
}
});
首次显示暗示性别&#39;定义布尔全局变量&#39; flag&#39;,
boolean flag = false; // Here
.
.
.
sexSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
if (flag) // Here
gender.setText(sexSpinner.getSelectedItem().toString());
}
});
.
.
.
gender.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
flag = true; // Here
sexSpinner.performClick();
}
});

你可以通过这个实现你想要的目标:
在xml中添加此项而不是edittext和spinner
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_dropdown_item_1line, GENDERLIST);
AutoCompleteTextView textView = (AutoCompleteTextView)
findViewById(R.id.gender_list);
textView.setAdapter(adapter);
textView.setOnTouchListener(new OnTouchListener() {
@SuppressLint("ClickableViewAccessibility")
@Override
public boolean onTouch(View paramView, MotionEvent paramMotionEvent) {
// TODO Auto-generated method stub
textView.showDropDown();
textView.requestFocus();
return false;
}
});
,这在你的java代码中
function SetButtonStatus() {
var Stat = document.getElementById('<%=_oTextBoxNRC.ClientID%>').value;
var Area = document.getElementById('<%=_oTextBoxArea.ClientID%>').value;
var Capital = document.getElementById('<%=_oTextBoxCapital.ClientID%>').value;
var Code = document.getElementById('<%= _oTextboxBusLineCode.ClientID%>').value;
var Gross = document.getElementById('<%=_oTextBoxGrossRec.ClientID%>').value;
//Change these conditions as your requirement
switch (Stat) {
case 'N':
if (parseFloat(Area) >= 1 && parseFloat(Capital) >= 1 && Code.length >= 1)
document.getElementById('<%=_oButtonAdd.ClientID%>').disabled = false;
else
document.getElementById('<%=_oButtonAdd.ClientID%>').disabled = true;
break;
case 'R':
if (parseFloat(Area) >= 1 && parseFloat(Gross) >= 1 && Code.length >= 1)
document.getElementById('<%=_oButtonAdd.ClientID%>').disabled = false;
else
document.getElementById('<%=_oButtonAdd.ClientID%>').disabled = true;
break;
}
}

你点击它时没有让微调器可见,所以你看不到它
sexSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view,int position, long id) {
sexSpinner.setVisibility(View.Invisible)
gender.setText(sexSpinner.getSelectedItem().toString());
}
gender.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View arg0, boolean hasFocus) {
// TODO Auto-generated method stub
if(hasFocus){
sexSpinner.setVisibility(View.Visible)
sexSpinner.performClick();
}
}
});

更改为对signup_input_gender使用AutoCompleteTextView,其showDropDown()将显示列表(在R.array.Gender_Names的资源中定义)
fun setupGenderWithDropdown() {
val genderEditText = findViewById(R.id.signup_input_gender)
val arrayAdapter = ArrayAdapter(
this, android.R.layout.simple_list_item_1, resources.getStringArray(R.array.Gender_Names)
)
genderEditText.setAdapter(arrayAdapter)
genderEditText.setOnClickListener {
genderEditText.showDropDown()
}
}
