我开发了一个复合视图,其中包含TextView,Imageview和EditText。我面临的问题是 EditText 在单击它时无法获得焦点以显示键盘,并且光标也不可见。我错过了什么?我也尝试过requestFocus和focusOnTouchMode,但它不起作用。以下是代码:
public class ExtendedInputField extends FrameLayout {
private LayoutExtendedInputFieldBinding itemViewBinding;
public ExtendedInputField(Context context) {
super(context);
initializeView(context, null, 0);
}
public ExtendedInputField(Context context, AttributeSet attrs) {
super(context, attrs);
initializeView(context, attrs, 0);
}
public ExtendedInputField(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
initializeView(context, attrs, defStyleAttr);
}
private void initializeView(Context context, AttributeSet attrs, int defStyleAttr) {
TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.ExtendedInputField, defStyleAttr, 0);
String hint = null, title = null, text = null;
int inputType = EditorInfo.TYPE_TEXT_VARIATION_NORMAL, imeOptions = -1, lines = 1;
boolean singleLine = true;
Drawable labelIcon = null;
try {
int n = a.getIndexCount();
for (int i = 0; i < n; i++) {
int attr = a.getIndex(i);
switch (attr) {
case R.styleable.ExtendedInputField_android_hint:
hint = a.getString(attr);
break;
case R.styleable.ExtendedInputField_android_inputType:
inputType = a.getInt(attr, EditorInfo.TYPE_TEXT_VARIATION_NORMAL);
break;
case R.styleable.ExtendedInputField_android_imeOptions:
imeOptions = a.getInt(attr, 0);
break;
case R.styleable.ExtendedInputField_android_lines:
lines = a.getInt(attr, 0);
break;
case R.styleable.ExtendedInputField_android_singleLine:
singleLine = a.getBoolean(attr, true);
break;
case R.styleable.ExtendedInputField_android_text:
text = a.getString(attr);
break;
case R.styleable.ExtendedInputField_title:
title = a.getString(attr);
break;
case R.styleable.ExtendedInputField_iconDrawable:
labelIcon = a.getDrawable(attr);
break;
default:
Log.d("ExtendedInputField", "Unknown attribute for " + getClass().toString() + ": " + attr);
break;
}
}
} finally {
a.recycle();
}
itemViewBinding = LayoutExtendedInputFieldBinding.inflate(LayoutInflater.from(context), this, true);
if (labelIcon != null) {
itemViewBinding.ivIcon.setImageDrawable(labelIcon);
}
if (!TextUtils.isEmpty(title))
itemViewBinding.tvTitle.setText(title);
if (!TextUtils.isEmpty(text))
itemViewBinding.etInput.setText(text);
if (!TextUtils.isEmpty(hint))
itemViewBinding.etInput.setHint(hint);
itemViewBinding.etInput.setInputType(inputType);
itemViewBinding.etInput.setSingleLine(singleLine);
itemViewBinding.etInput.setLines(lines);
if (imeOptions != -1)
itemViewBinding.etInput.setImeOptions(imeOptions);
}
@Override
protected void onFinishInflate() {
super.onFinishInflate();
addEditTextListener();
}
private void addEditTextListener() {
itemViewBinding.etInput.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
itemViewBinding.etInput.setCursorVisible(true);
}
});
}
public void setIcon(@DrawableRes int resId) {
itemViewBinding.ivIcon.setImageResource(resId);
}
public void setTitle(@StringRes int resId) {
itemViewBinding.tvTitle.setText(resId);
}
public void setTitle(String text) {
itemViewBinding.tvTitle.setText(text);
}
public EditText getEditText() {
return itemViewBinding.etInput;
}
public String getText() {
return itemViewBinding.etInput.getText().toString();
}
public void setText(String text) {
if (text != null)
itemViewBinding.etInput.setText(text);
}
}
以下是 xml 代码:
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">

android:layout_width="20dp"
android:layout_height="20dp"
android:src="@drawable/icon_email"
app:layout_constraintBottom_toBottomOf="@+id/tvTitle"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="@+id/tvTitle" />
<TextView
android:id="@+id/tvTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="11.3dp"

android:textSize="@dimen/extended_input_field_title_size"

<EditText

</androidx.constraintlayout.widget.ConstraintLayout>
</layout>
我遇到了同样的问题。
不知道为什么,但注释掉输入类型:"TYPE_TEXT_VARIATION_NORMAL"解决了这个问题。看看它是否适合你。
使用 android:cursorVisible="false"
用于删除 EditText 闪烁光标,因此请使用 android:cursorVisible="true"
.如果要以编程方式添加它,请使用此mEditText.setCursorVisible(true)
