今天的我得交我的个人作业了。或者我还可以拖两天？

我觉得我得拖两天。

public class MainActivity extends AppCompatActivity implements View.OnClickListener,CompoundButton.OnCheckedChangeListener{

    private CheckBox cb_one;
    private CheckBox cb_two;
    private CheckBox cb_three;
    private Button btn_send;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        cb_one = (CheckBox) findViewById(R.id.cb_one);
        cb_two = (CheckBox) findViewById(R.id.cb_two);
        cb_three = (CheckBox) findViewById(R.id.cb_three);
        btn_send = (Button) findViewById(R.id.btn_send);

        cb_one.setOnCheckedChangeListener(this);
        cb_two.setOnCheckedChangeListener(this);
        cb_three.setOnCheckedChangeListener(this);
        btn_send.setOnClickListener(this);

    }

    @Override
    public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
       if(compoundButton.isChecked()) Toast.makeText(this,compoundButton.getText().toString(),Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onClick(View view) {
        String choose = "";
        if(cb_one.isChecked())choose += cb_one.getText().toString() + "";
        if(cb_two.isChecked())choose += cb_two.getText().toString() + "";
        if(cb_three.isChecked())choose += cb_three.getText().toString() + "";
        Toast.makeText(this,choose,Toast.LENGTH_SHORT).show();
    }
}
