Kotlin

Question

我在下面创建了 class 以在我的普通 EditText 中设置自定义字体或任何 otf 字体。我正在使用 kotlin 并在下面创建 class 以推广使用 CustomEditText。

我在资产中添加了字体文件并在下面创建了 class 名为 CustomEditText:

import android.content.Context
import android.content.res.TypedArray
import android.graphics.Typeface
import android.util.AttributeSet
import androidx.appcompat.widget.AppCompatEditText

class CustomEditText : AppCompatEditText{

constructor(context: Context) : this(context, null) {
    init(null)
}

constructor(context: Context, attrs: AttributeSet?) : this(context, attrs, 0) {
    init(attrs)
}

constructor(context: Context, attrs: AttributeSet?, defStyleAttr: Int) : super(
    context,
    attrs,
    defStyleAttr
) {
    init(attrs)
}

private fun init(attrs: AttributeSet?) {
    CustomEditText(context, attrs, 0)
}

/**
 * @param context:This is an abstract class whose implementation is provided by Android Operating System.
 * @param attrs:A collection of attributes, as found associated with a tag in an XML document.
 * @param defStyle:
 */
fun CustomEditText(
    context: Context,
    attrs: AttributeSet?,
    defStyle: Int
) {
    try {
        val a: TypedArray =
            context.obtainStyledAttributes(attrs, R.styleable.CustomEditText, defStyle, 0)
        val customEnumValue: CustomEnumBrandonNew.CustomFontType =
            CustomEnumBrandonNew.CustomFontType.fromId(
                a.getInt(
                    R.styleable.CustomEditText_font_type,
                    0
                )
            )
        a.recycle()
        typeface = when (customEnumValue) {
            CustomEnumBrandonNew.CustomFontType.BLACK ->
                Typeface.createFromAsset(context.assets, "BrandonText-Black.otf") // BrandonTextBlack().getInstance(context)?.getTypeFace()
            CustomEnumBrandonNew.CustomFontType.BLACK_ITALIC ->
                Typeface.createFromAsset(context.assets, "BrandonText-BlackItalic.otf") // BrandonTextBlackItalic().getInstance(context)?.getTypeFace()
            CustomEnumBrandonNew.CustomFontType.BOLD ->
                Typeface.createFromAsset(context.assets, "BrandonText-Bold.otf") // BrandonTextBold().getInstance(context)?.getTypeFace()
            CustomEnumBrandonNew.CustomFontType.BOLD_ITALIC ->
                Typeface.createFromAsset(context.assets, "BrandonText-BoldItalic.otf") // BrandonTextBoldItalic().getInstance(context)?.getTypeFace()
            CustomEnumBrandonNew.CustomFontType.LIGHT ->
                Typeface.createFromAsset(context.assets, "BrandonText-Light.otf") // BrandonTextBoldItalic().getInstance(context)?.getTypeFace()
            CustomEnumBrandonNew.CustomFontType.LIGHT_ITALIC ->
                Typeface.createFromAsset(context.assets, "BrandonText-LightItalic.otf") // BrandonTextBoldItalic().getInstance(context)?.getTypeFace()
            CustomEnumBrandonNew.CustomFontType.MEDIUM ->
                Typeface.createFromAsset(context.assets, "BrandonText-Medium.otf") // BrandonTextBoldItalic().getInstance(context)?.getTypeFace()
            CustomEnumBrandonNew.CustomFontType.MEDIUM_ITALIC ->
                Typeface.createFromAsset(context.assets, "BrandonText-MediumItalic.otf") // BrandonTextBoldItalic().getInstance(context)?.getTypeFace()
            CustomEnumBrandonNew.CustomFontType.REGULAR ->
                Typeface.createFromAsset(context.assets, "BrandonText-Regular.otf") // BrandonTextBoldItalic().getInstance(context)?.getTypeFace()
            CustomEnumBrandonNew.CustomFontType.REGULAR_ITALIC ->
                Typeface.createFromAsset(context.assets, "BrandonText-RegularItalic.otf") // BrandonTextBoldItalic().getInstance(context)?.getTypeFace()
            CustomEnumBrandonNew.CustomFontType.THIN ->
                Typeface.createFromAsset(context.assets, "BrandonText-Thin.otf") // BrandonTextBoldItalic().getInstance(context)?.getTypeFace()
            CustomEnumBrandonNew.CustomFontType.THIN_ITALIC ->
                Typeface.createFromAsset(context.assets, "BrandonText-ThinItalic.otf") // BrandonTextBoldItalic().getInstance(context)?.getTypeFace()
        }
    } catch (e: Exception) {
        e.printStackTrace()
    }
}
}

在此之前，我还创建了单独的 classes，即 BrandonTextBlack、BrandonTextBlackItalic、BrandonTextBold 等如下：

class BrandonTextBold{

private var instance: BrandonTextBold? = null
private var typeface: Typeface? = null

fun getInstance(context: Context): BrandonTextBold? {
    synchronized(BrandonTextBold::class.java) {
        if (instance == null) {
            typeface = Typeface.createFromAsset(context.resources.assets, "BrandonText-Bold.otf")
        }
        return instance
    }
}

fun getTypeFace(): Typeface? {
    return typeface
}

}

现在，在布局 xml 文件中，如下使用它：

<CustomEditText
            android:id="@+id/edt_mobile_number"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_marginTop="@dimen/dimen_40"
            android:background="@drawable/drawable_round_button_transperent"
            android:hint="@string/str_hint_enter_your_mobile_number"
            android:imeOptions="actionDone"
            android:inputType="number|phone"
            android:maxLength="10"
            android:textColorHint="@color/colorHintAndBorder"
            android:maxLines="1"
            android:paddingBottom="@dimen/dimen_8"
            android:paddingTop="@dimen/dimen_8"
            android:paddingRight="@dimen/dimen_15"
            android:paddingLeft="@dimen/dimen_15"
            android:textColor="@color/colorBlack"
            android:textSize="@dimen/font_dimen_20"
            app:font_type="regular" />

这里注意我用了app:font_type="regular"。所以，我可以在我的 edittext 中使用正常的字体类型。完成。

但是，问题是当我按下或尝试在其中输入内容时，软键盘无法打开。

可能是什么问题？

Answer 1

在所有构造函数中使用默认样式作为 EditText 样式，而不是 0

来自

 constructor(context: Context, attrs: AttributeSet?) : this(context, attrs, 0) {
        init(attrs)
    }

至

constructor(context: Context, attrs: AttributeSet?) : this(context, attrs, android.R.attr.editTextStyle) {
        init(attrs)
    }
