這個問題google了一下织堂，答案都是一樣的叠艳。但在使用過程中，發(fā)現(xiàn)在有虛擬鍵的情況下有問題易阳。所以自己做了進一步優(yōu)化附较。自己測試通過的機型有紅米note5plus、華為p9潦俺、魅藍note2拒课、榮耀V8、華為nova2 plus事示。

完整代碼如下:

/*全屏模式下早像，即使將activity的windowSoftInputMode的屬性設(shè)置為：adjustResize，
在鍵盤顯示時它未將Activity的Screen向上推動肖爵，所以你Activity的view的根樹的尺寸是沒有變化的卢鹦。
在這種情況下，你也就無法得知鍵盤的尺寸遏匆，對根view的作相應(yīng)的推移法挨。全屏下的鍵盤無法Resize的問題從2.1就已經(jīng)存在了，直到現(xiàn)在google還未給予解決幅聘。*/

在Activity中使用:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_confirm_order);

        ButterKnife.bind(this);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            //沉浸式狀態(tài)欄
            immersionBar = ImmersionBar.with(this).statusBarDarkFont(true, 0.2f);
            immersionBar.init();

            bug5497Workaround = AndroidBug5497Workaround.init(this);
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (immersionBar != null) {
            immersionBar.destroy();
        }
        if (presenter != null) {
            presenter.destory();
        }
        if(bug5497Workaround!=null){
            bug5497Workaround.destory();
        }
    }
