自定义EditText不在焦点上显示键盘 [英] Custom EditText is not showing keyboard on focus
问题描述
我正在创建一个自定义EditText类,因为我需要设置一些自定义字体.但是现在当我单击editText时,Android键盘不再弹出...
I am creating a custom EditText class because i need to set some custom fonts; However now when i click on the editText the android keyboard does not pop up anymore...
这是我的课程:
package ro.gebs.captoom.utils.fonts;
import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Rect;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.view.inputmethod.InputMethodManager;
import android.widget.EditText;
import ro.gebs.captoom.R;
public class CustomFontEditText extends EditText {
private Context context;
public CustomFontEditText(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
if (!isInEditMode()) {
TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.CustomFontEditText,
defStyle, 0);
assert a != null;
int fontId = a.getInteger(R.styleable.CustomFontEditText_fontNameEdit, -1);
if (fontId == -1) {
throw new IllegalArgumentException("The font_name attribute is required and must refer "
+ "to a valid child.");
}
a.recycle();
initialize(fontId);
}
this.context = context;
}
public CustomFontEditText(Context context, AttributeSet attrs) {
this(context, attrs, 0);
this.context = context;
}
public CustomFontEditText(Context context) {
super(context);
this.context = context;
}
@SuppressWarnings("ConstantConditions")
public void initialize(int fontId) {
Typeface tf = null;
switch (fontId) {
case 0:
tf = Typeface.createFromAsset(getContext().getAssets(), "fonts/OpenSans-Regular.ttf");
break;
case 1:
tf = Typeface.createFromAsset(getContext().getAssets(), "fonts/OpenSans-Bold.ttf");
break;
case 2:
tf = Typeface.createFromAsset(getContext().getAssets(), "fonts/OpenSans-Semibold.ttf");
break;
case 3:
tf = Typeface.createFromAsset(getContext().getAssets(), "fonts/OpenSans-ExtraBold.ttf");
break;
}
setTypeface(tf);
}
}
以及如何在XML中使用它:
and how i use it in XML:
<ro.gebs.captoom.utils.fonts.CustomFontEditText
android:id="@+id/add_details_txt_edit"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dip"
android:hint="@string/type_here"
android:inputType="textPersonName"
custom:fontNameEdit="Regular" />
我认为聚焦事件是因为我扩展了EditText类...
I thought the focusing events were handled by the fact that i extend the EditText class...
有任何提示吗?
推荐答案
这是一个老问题,但如果有人在乎,那么问题就出在构造函数的实现上:
It's an old question but if someone cares, the problem is on the implementation of the constructor:
public CustomFontEditText(Context context, AttributeSet attrs) {
this(context, attrs, 0);
this.context = context;
}
您设置为0的最后一个参数("defStyle")应该是EditText的默认样式.如果您在EditText类上查看相同的构造函数:
The last argument ("defStyle") which you set as 0, should be the default style for an EditText. If you take a look at the same constructor on the EditText class:
public EditText(Context context, AttributeSet attrs) {
this(context, attrs, com.android.internal.R.attr.editTextStyle);
}
如您所见,应使用EditText的默认样式,因此您的构造函数应如下所示:
As you can see, the default style for an EditText should be used, so your constructor should look like this:
public CustomFontEditText(Context context, AttributeSet attrs) {
this(context, attrs, android.R.attr.editTextStyle);
this.context = context;
}
