Java 代码

在 LoginFragment.java 中

 //decleration within the fragment class 
    ImageView iv_g;
    ImageView iv_fb;
    ImageView iv_t;

来自 onCreateView 方法

    View view = inflater.inflate(R.layout.fragment_login, container, false);
    iv_fb = (ImageView) view.findViewById(R.id.iv_fbm);
    iv_t = (ImageView) view.findViewById(R.id.iv_tm);
    iv_g = (ImageView) view.findViewById(R.id.iv_googlem);
    iv_fb.setOnClickListener(this);
    iv_g.setOnClickListener(this);
    iv_t.setOnClickListener(this);

来自 onClick 方法

      if (v.getId() == R.id.iv_googlem) {
            Toast.makeText(context, "google", Toast.LENGTH_SHORT).show();
            Intent intent = new Intent(context, MyService.class);
            intent.putExtra("type", "google");
            context.startService(intent);
        } else if (v.getId() == R.id.iv_fbm) {
            Toast.makeText(context, "facebook", Toast.LENGTH_SHORT).show();

            Intent intent = new Intent(context, MyService.class);
            intent.putExtra("type", "facebook");
            context.startService(intent);
        } else if (v.getId() == R.id.iv_tm) {
            Toast.makeText(context, "twitter", Toast.LENGTH_SHORT).show();

            Intent intent = new Intent(context, MyService.class);
            intent.putExtra("type", "twitter");
            context.startService(intent);
        }

3 个按钮可以正常工作，但是单击时 3 个 ImageViews 不会触发

Answer 1

试试这个语法，看看它是否有效：

iv_fb.setOnClickListener(new view.OnClickListener{    public void onClick()
    {
          Toast.makeText(context, "google", Toast.LENGTH_SHORT).show();
          Intent intent = new Intent(context, MyService.class);
          intent.putExtra("type", "google");
          context.startService(intent);
    } });
