public MyNumPan(Context context, @Nullable AttributeSet attrs) {

@Override

}
然后在布局里面
在代码里面
private EditText et_qujian_code;
et_qujian_code = view.findViewById(R.id.et_qujian_code); MyNumPan numPan = view.findViewById(R.id.pan); numPan.bindEditText(et_qujian_code); numPan.setOnCompleteListener(this);
@Override
public void onClick(View v)
{
mvpPresenter.getfetchParcel();
}
如果有两个输入框
et_qujian_pwd_code=view.findViewById(R.id.et_qujian_pwd_send);
et_qujian_phone_code=view.findViewById(R.id.et_qujian_phone_send);
numPan= view.findViewById(R.id.pan);
et_qujian_pwd_code.setOnFocusChangeListener(new View.OnFocusChangeListener()
{
@Override
public void onFocusChange(View v, boolean hasFocus)
{
numPan.bindEditText(et_qujian_pwd_code);
}
});
et_qujian_phone_code.setOnFocusChangeListener(new View.OnFocusChangeListener()
{
@Override
public void onFocusChange(View v, boolean hasFocus)
{
numPan.bindEditText(et_qujian_phone_code);
}
});
numPan.setOnCompleteListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
mvpPresenter.fetchOpenBox();
}
});
