Android 中隐藏虚拟按键的方法实例代码

下面通过一段代码给大家讲解android 隐藏虚拟按键的方法，废话不多说了，大家多多看看代码和注释吧，具体代码如下所示：

 /**
   * 隐藏虚拟按键，并且全屏
   */
  protected void hidebottomuimenu() {
    //隐藏虚拟按键，并且全屏
    if (build.version.sdk_int > 11 && build.version.sdk_int < 19) { // lower api
      view v = this.getwindow().getdecorview();
      v.setsystemuivisibility(view.gone);
    } else if (build.version.sdk_int >= 19) {
      //for new api versions.
      view decorview = getwindow().getdecorview();
      int uioptions = view.system_ui_flag_hide_navigation
          | view.system_ui_flag_immersive_sticky | view.system_ui_flag_fullscreen;
      decorview.setsystemuivisibility(uioptions);
    }
  }

//隐藏虚拟按键，并且全屏
    getwindow().getdecorview().setsystemuivisibility(view.system_ui_flag_hide_navigation
        | view.system_ui_flag_immersive_sticky | view.system_ui_flag_fullscreen);
    getwindow().getdecorview().setonsystemuivisibilitychangelistener(new view.onsystemuivisibilitychangelistener() {
      @override
      public void onsystemuivisibilitychange(int visibility) {
        getwindow().getdecorview().setsystemuivisibility(view.system_ui_flag_hide_navigation
            | view.system_ui_flag_immersive_sticky | view.system_ui_flag_fullscreen);
      }
    });

例子

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); 
    } 
  } 
}
