定义一个有参方法，参数包含path还有handler不知道怎么处理

package com.example.felix.myapplication;

public class HomewActivity extends AppCompatActivity implements View.OnClickListener {

    public static final String PATH = "https://img1.sycdn.imooc.com//5adfee7f0001cbb906000338-240-135.jpg";

        button.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        switch (view.getId()){
            case R.id.getPicture_button:
                GetPicThread(PATH, com.example.felix.myapplication.HomewActivity.mHandler);
                break;
        }
    }

    private void GetPicThread(final String path, final Handler handler) {
        new Thread(new Runnable() {
            @Override
            public void run() {
                try {

                    HttpURLConnection connection=(HttpURLConnection)url.openConnection();
                    connection.setConnectTimeout(30*1000);

                        handler.sendMessage(message);
                    }

                } catch (MalformedURLException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }).start();
    }


    public static class mHandler extends Handler{
        final WeakReference<HomewActivity> mWeakReference;

        public mHandler(HomewActivity activity) {
            mWeakReference=new WeakReference<>(activity);
        }

        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            HomewActivity activity=mWeakReference.get();
            if(msg.what== INT){
                activity.imageView.setImageBitmap((Bitmap) msg.obj);

            }
        }
    }
}

你理解错了，意思是图中的这两个参数，是通过方法传进来的。你调用 GetPicThread( )时传递进来的。而不是在GetPicThread（）中自己写死，这样方法更灵活嘛，易扩张。祝：学习愉快
