How can i go to an other activity when i click button of list view?

问题

我想要将两个不同的活动意图（FreeLine、MoveCircle）。

如果我点击开始按钮，它将始终启动 FreeLine。

如何在点击列表视图的按钮时切换到另一个活动？

如何区分这些意图..？

  1.     @Override
  2.     public View getView(final int position, View convertView, ViewGroup parent) {
  3.         final Context context = parent.getContext();
  5.         if (convertView == null) {
  6.             LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
  7.             convertView = mInflater.inflate(mLayout, parent, false);
  8.         }
  10.         ImageView img = (ImageView)convertView.findViewById(R.id.img);
  11.         img.setImageResource(mDatas.get(position).Img);
  13.         TextView txt = (TextView)convertView.findViewById(R.id.text);
  14.         txt.setText(mDatas.get(position).Name);
  16.         TextView txt2 = (TextView)convertView.findViewById(R.id.desc);
  17.         txt2.setText(mDatas.get(position).Des);
  19.         Button btn = (Button)convertView.findViewById(R.id.btn);
  20.         btn.setOnClickListener(new View.OnClickListener() {
  21.             @Override
  22.             public void onClick(View v) {
  23.                 // 如何分开这两个意图？
  24.                 Intent FreeLineIntent = new Intent(v.getContext(), FreeLine.class);
  25.                 mContext.startActivity(FreeLineIntent);
  26.                 Intent MoveCircleIntent = new Intent(v.getContext(), MoveCircle.class);
  27.                 mContext.startActivity(MoveCircleIntent);
  28.             }
  29.         });

How to separate these intents..?

  1.     @Override
  2. public View getView(final int position, View convertView, ViewGroup parent) {
  3. final Context context = parent.getContext();
  4. if (convertView == null) {
  5. LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
  6. convertView = mInflater.inflate(mLayout, parent, false);
  7. }
  8. ImageView img = (ImageView)convertView.findViewById(R.id.img);
  9. img.setImageResource(mDatas.get(position).Img);
  10. TextView txt = (TextView)convertView.findViewById(R.id.text);
  11. txt.setText(mDatas.get(position).Name);
  12. TextView txt2 = (TextView)convertView.findViewById(R.id.desc);
  13. txt2.setText(mDatas.get(position).Des);
  14. Button btn = (Button)convertView.findViewById(R.id.btn);
  15. btn.setOnClickListener(new View.OnClickListener() {
  16. @Override
  17. public void onClick(View v) {
  18. //How to separate these two intents???
  19. Intent FreeLineIntent = new Intent(v.getContext(), FreeLine.class);
  20. mContext.startActivity(FreeLineIntent);
  21. Intent MoveCircleIntent = new Intent(v.getContext(), MoveCircle.class);
  22. mContext.startActivity(MoveCircleIntent);
  23. }

  5. //How to separate these two intents???
  6. String txtTitle = txt2.getText().toString();
  7. switch (txtTitle){
