Question

所以，我有这个“next”按钮调用一个字符串数组，当count到达“-1”时，我想开始一个新的视图。我怎么能这样做？

    Button nextButton = (Button) findViewById(R.id.next_button);
     nextButton.setOnClickListener(new View.OnClickListener() {
         public void onClick(View view) {
            if (count < myString.length) {
                 lessonsDialog.setText(myString[count]);
                 count++;
             } else {
                 if (count < myString.length  [-1]) {
                     handler2.sendEmptyMessageDelayed(MESSAGE_SHOW_POPUP2, TIME_DELAY2);
                 }
             }
         }
     });

Answer 1

可能你想开始新的活动。

Intent intent = new Intent(getApplicationContext(), YourClassName.class);
startActivity(intent);

Answer 2

LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View viewName = inflater.inflate(R.layout.YOUR_VIEW_ID, null, false);

使用方法addView（View child）和removeView（View view）来添加和删除视图。

Answer 3

Нou可以调用removeView（View child）;和addView（View child）;在ViewGroup上。

示例

LinearLayout viewHolder = (Linearlayout) findViewById(R.id.view_holder);

LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

View viewBeforeClick = inflater.inflate(R.layout.YOUR_VIEW_ID1, null, false);
View viewAfterClick = inflater.inflate(R.layout.YOUR_VIEW_ID2, null, false);

viewHolder.addView(viewBeforeClick);

//when clicked on next button

viewHolder.removeView(viewBeforeClick);
viewHolder.addView(viewAfterClick);

字符串数组完成后开始一个新视图
