本文介绍如何在Android应用中使用系统UI属性隐藏导航栏，并通过点击操作切换不同的显示状态。

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;

public class HideTestActivity extends Activity implements OnClickListener{
View main ;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      main = getLayoutInflater().from(this).inflate(R.layout.main, null);
      main.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
      main.setOnClickListener(this);
      setContentView(main);
}

@Override
public void onClick(View v) {
      int i = main.getSystemUiVisibility();
      if (i == View.SYSTEM_UI_FLAG_HIDE_NAVIGATION) {
         main.setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE);
      } else if (i == View.SYSTEM_UI_FLAG_VISIBLE){
         main.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE);
      } else if (i == View.SYSTEM_UI_FLAG_LOW_PROFILE) {
         main.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
      }
}

}
