java - for 循环的 onClickListener 不起作用

Question

变量 i 没有递增，如果答案正确，那么我想通过递增变量 i 来问另一个问题。我实现了 OnClickListner 但没有发生任何事情。我是安卓新手，谢谢。

public class MainActivity extends AppCompatActivity{

        ImageView car, icecream, pencil, umbrella, ball;
        TextView question, answer;
        int i, size, j;
        final String[] objects  = {"car", "icecream", "pencil", "ball","umbrella"};

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            setContentView(R.layout.activity_main);

           final Animation expandIn = AnimationUtils.loadAnimation(this, R.anim.expand_in);




            size = objects.length;
            car = (ImageView) findViewById(R.id.car);

            umbrella = (ImageView) findViewById(R.id.umbrella);

            icecream = (ImageView) findViewById(R.id.icecream);

            pencil = (ImageView) findViewById(R.id.pencil);

            ball = (ImageView) findViewById(R.id.ball);

            question = (TextView) findViewById(R.id.question);
            answer = (TextView) findViewById(R.id.answer);

            j=0;
            for (i=0; i < size; i++)

            {

                if(i == j){
                    question.setText("");
                    question.setText("Where is "+objects[i]+" ?");

Answer 1

您将在 j = j+1 之后脱离 for 循环
