m300飞机h200t切换红外镜头无效的问题

bt_infrared_300.setOnClickListener(new View.OnClickListener() {

                if (djiError != null)
                    Log.i("qqqqq错误3", djiError.getDescription());
            }
        });


        if (bt_infrared_300.getText().toString().equals("红外")) {
            DroneModelFactory.getProductInstance().getCamera().getLens(2).setDisplayMode(SettingsDefinitions.DisplayMode.THERMAL_ONLY, new CommonCallbacks.CompletionCallback() {

                            bt_infrared_300.setText("红外");
                        }
                    });

                }
            });
        }

    }

写了一按钮，点击以后将红外镜头切换成分屏或者全屏。但代码如上，进入点击按钮由全屏切换成分屏无效。但将切换的代码拿到点击事件外时，进入该页面，是可以正常设置为分屏的。后来我用两个按钮，一个设置分屏，一个设置全屏，设置全屏没有问题，但是设置分屏需要点击两次才可以设置成功，请问这是什么原因导致的，要怎么修改呢
