Android 部分机型没有物理按键，只有虚拟按键，Activity全屏方法如下：

1、在

setContentView(R.layout.activity_main);之前添加

getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);

2、当用户划出虚拟按键后，自动再隐藏方法如下：

getWindow().getDecorView().setOnSystemUiVisibilityChangeListener(new OnSystemUiVisibilityChangeListener() {    @Override    public void onSystemUiVisibilityChange(int visibility) {        int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE |                //布局位于状态栏下方                View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION |                //全屏                View.SYSTEM_UI_FLAG_FULLSCREEN |                //隐藏导航栏                View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |                View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN;        if (Build.VERSION.SDK_INT >= 19) {            uiOptions |= 0x00001000;        } else {            uiOptions |= View.SYSTEM_UI_FLAG_LOW_PROFILE;        }        getWindow().getDecorView().setSystemUiVisibility(uiOptions);    }});

3、dialog 隐藏方法

mDialog.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);mDialog.getWindow().getDecorView().setOnSystemUiVisibilityChangeListener(new OnSystemUiVisibilityChangeListener() {    @Override    public void onSystemUiVisibilityChange(int visibility) {        int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE |                //布局位于状态栏下方                View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION |                //全屏                View.SYSTEM_UI_FLAG_FULLSCREEN |                //隐藏导航栏                View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |                View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN;        if (Build.VERSION.SDK_INT >= 19) {            uiOptions |= 0x00001000;        } else {            uiOptions |= View.SYSTEM_UI_FLAG_LOW_PROFILE;        }        mDialog.getWindow().getDecorView().setSystemUiVisibility(uiOptions);    }});要在mDialog.show();之前。
