我想在同一活动中创建一个活动,其中包含“20张随机图像+每张图片下方4个按钮”(但另外)。 所以,我使用“ for loop ”来做到这一点。
现在,当用户点击其中一个按钮,然后创建一个图像和另一个随机按钮时,我想 回到循环的开头 应用
请指导我解决此问题。
感谢。
代码:
注意:此代码无法正常工作,因为以下声明不起作用:
if (clk==true) continue;
public class testActivity extends Activity {
int falseb;
boolean clk=false;
String truename;
final Random rnd = new Random();
// public String[] picture={"banana","black","camel","cherry"};
String [] picture = new String [] {"camel1","cat1","monkey","dogs" };
List<String> List = new ArrayList<String>(Arrays.asList(picture));
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
final ImageView img = (ImageView) findViewById(R.id.imgRandom);
final Button b1 = (Button) findViewById(R.id.b1);
final Button b2 = (Button) findViewById(R.id.b2);
final Button b3 = (Button) findViewById(R.id.b3);
final Button b4 = (Button) findViewById(R.id.b4);
Typeface font = Typeface.createFromAsset(getAssets(), "koodk.ttf");
b1.setTypeface(font);
b2.setTypeface(font);
b3.setTypeface(font);
b4.setTypeface(font);
for (int num=1;num<20;num++) {
//set Image and 4 options(as Button)by random
b1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
clk=true;
if (((Button) view).getText()==truename){
((Button) view).setBackgroundResource(R.mipmap.true1);
List.remove(rp);
}else {
((Button) view).setBackgroundResource(R.mipmap.fls1);
List.remove(rp);clk=true;
}
}
});
b2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {clk=true;
if (((Button) view).getText()==truename){
((Button) view).setBackgroundResource(R.mipmap.true1);

答案 0 :(得分:3)
Try to
for(int i = 0; i < 20; i++){
if(response == false){
//regenerate your list here
i = 0;
}
}
