方法不适用参数

Question

老师，我要做的是点击一个按钮出现进度提示框5秒后消失 出现错误：The method show(Context, CharSequence, CharSequence) in the type ProgressDialog is not applicable for the arguments (new View.OnClickListener(){}, String, String)我的代码是：bt1 = (Button)findViewById(R.id.button2);        et1 = (EditText) findViewById(R.id.editText1);                bt1.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { final ProgressDialog dialog = ProgressDialog.show(this, "Doing something","P;ease wait..."); new Thread(new Runnable() { @Override public void run() { try{ Thread.sleep(5000); dialog.dismiss(); }catch (InterruptedException e){ e.printStackTrace(); } } }).start(); } });麻烦老师帮我看一下吧
