自定義數字鍵盤

首先 自定義鍵盤

 

public class MyNumPan extends LinearLayout implements View.OnClickListener {
    Button btn_0;
    Button btn_1;
    Button btn_2;
    Button btn_3;
    Button btn_4;

        array.recycle();
        btn_0.setOnClickListener(this);

//                } else {
//                    editText.append(".");
//                }
//                break;
            case R.id.button_clear:
                editText.setText("");
                break;
            case R.id.button_complete:
                if (completeListener != null) {
                   completeListener.onClick(v);
                }
                break;
        }
    }
}

而後在佈局裏面

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="bottom"
    android:orientation="vertical"
    android:gravity="bottom">

    <com.hatai.smartlokey.utils.keybord.MyNumPan
        android:id="@+id/pan"
        android:layout_width="match_parent"
        android:layout_height="@dimen/px300"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:layout_marginTop="@dimen/px50"
        app:button_name="Done"/>
</LinearLayout>

 

在代碼裏面

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();

}

若是有兩個輸入框

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();
    }
});
