自定义EditText未在焦点上显示键盘

我正在创建一个自定义的EditText类,因为我需要设置一些自定义字体;但是现在当我点击editText时,android键盘不再弹出......

这是我的班级:

    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);
    }
}

以及我如何在XML中使用它:

<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" />

我认为聚焦事件是由我扩展EditText类...

的事实处理的

任何提示?

答案 0 :(得分:71)

这是一个老问题,但如果有人关心,问题在于构造函数的实现:

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。如果你看看EditText类上的相同构造函数:

public EditText(Context context, AttributeSet attrs) {
    this(context, attrs, com.android.internal.R.attr.editTextStyle);
}

如您所见,应该使用EditText的默认样式,因此您的构造函数应如下所示:

public CustomFontEditText(Context context, AttributeSet attrs) {
    this(context, attrs, android.R.attr.editTextStyle);
    this.context = context;
}

使用 Kotlin 制作自定义EditText来解决焦点问题:

class MyEditText @JvmOverloads constructor(
context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = android.R.attr.editTextStyle) : AppCompatEditText(context, attrs, defStyleAttr) {


 init {
    doSomething(context)
 }

 private fun doSomething(context: Context) {
   // TODO Set your custom font or whatever you need
 }

}

添加此

 android:focusable="true"

答案 3 :(得分:0)

implements KeyListener on your custom EditText Class and override methods of KeyListener

答案 4 :(得分:0)

尝试在运行时编辑文本参考并调用请求焦点()

    et.requestFocus()

并尝试

   android:focusable="true"

答案 5 :(得分:-3)

 editText.setOnTouchListener(new OnTouchListener() 
  {
    @Override
    public boolean onTouch(View v, MotionEvent event) 
     {
         editText.setFocusableInTouchMode(true);
         return false;
     }
  });
