工作中遇到了自定义软键盘的场景，虽然简单很快就实现了，但对个别的细节不太满意。
因为细节决定成败，所以细节之处也不能忽视。
先来张效果图吧：
- key的相关属性：
- row的相关属性：
- KeyboardView的相关属性：
- ASCII码对应表：
我对这个自定义软键盘做了个简单的封装，使用起来也很简单。以下是我的自定义软键盘View类：
代码语言：javascript复制package com.newcapec.visitorsystem.diyview;
import android.app.Activity;
import android.inputmethodservice.Keyboard;
import android.inputmethodservice.KeyboardView;
import android.text.Editable;
import android.text.InputType;
import android.util.Log;
import android.view.View;
import android.view.WindowManager;
import android.widget.EditText;
import com.newcapec.cardliarbry.VistorCardController;
import com.newcapec.visitorsystem.R;

}布局文件如下：

</Keyboard>使用也很简单：

@Override
public boolean onTouch(View view, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP) {
abcNumberViewb.setOkListener(edtInputPhoneOkListener);
abcNumberViewb.setmEdit( mainBinding.includeBackscreenSearchLayout.edtInputPhone);
if(!abcNumberViewb.isShow()){
abcNumberViewb.showKeyboard();
}
}
return false;
}
});
