在膨胀的视图上执行事件（如OnClickListener）

Question

我想搬到其他班级.. 点击膨胀的视图时。

这是来源......

LayoutInflater inflater = (LayoutInflater)screen.getSystemService(screen.LAYOUT_INFLATER_SERVICE);
                    layout =  inflater.inflate(R.layout.log_viewer, null);

                    AlertDialog.Builder builder = new AlertDialog.Builder(Log_Activity.this);
                    builder.setView(layout);

                    AlertDialog alertDialog = builder.create(); 
                    alertDialog.show();
                    Button chat = (Button)findViewById(R.id.Chat);
                    chat.setOnClickListener(new OnClickListener() {

                        @Override
                        public void onClick(View v) {

                            Intent i =new Intent(Log_Activity.this,Text_chat.class);
                            startActivity(i);
                                                        }
                    })  ;
                    WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
                    Window window = alertDialog.getWindow();
                    lp.copyFrom(window.getAttributes());

                    lp.width = WindowManager.LayoutParams.MATCH_PARENT;
                    lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
                    window.setAttributes(lp);

按下按钮后，它突然崩溃。 有人可以帮帮我吗？
