解決全屏下中輸入框被鍵盤遮擋

最近項目遇到了中使用輸入框，但是輸入框被遮擋的問題，于是上網百度了一下，發現大多數的解決方式無非兩種，一種是代碼編輯，另一種是配置清單文件。

1、在所在的中加入

().(..SIZE|..DEN);

2、調整.xml

找到對應的，加入以下屬性

:=""

若此時還有全屏屬性:theme="@:style/Theme.."評論輸入框測試點，則刪除全屏屬性。

原因：軟鍵盤彈出時，要對主窗口布局重新進行布局，并調用方法，當設置為全屏模式，官方有說明，會忽略輸入框調整。

3.布局xml調整

控件所在的布局，祖先節點不能有。另外，根節點不能固定高度。還有，當根節點是時，本身、

父節點不能固定高度。

當然上述辦法本人都試過評論輸入框測試點，但是是無效的，主要是因為我的項目是需要全屏設置的，所以是不能按照方法2那樣直接刪除全屏設置，于是乎，便繼續搜索到

了另一種方法。方法如下：

public class KeyBoardListener {
    private Activity activity;
// private Handler mhanHandler;
    private View mChildOfContent;
    private int usableHeightPrevious;
    private FrameLayout.LayoutParams frameLayoutParams;
    private static KeyBoardListener keyBoardListener;
    public static KeyBoardListener getInstance(Activity activity) {
// if(keyBoardListener==null){
        keyBoardListener=new KeyBoardListener(activity);

// }
        return keyBoardListener;
    }
    public KeyBoardListener(Activity activity) {
        super();
// TODO Auto-generated constructor stub
        this.activity = activity;
// this.mhanHandler = handler;
    }
    public void init() {

        FrameLayout content = (FrameLayout) activity
                .findViewById(android.R.id.content);
        mChildOfContent = content.getChildAt(0);
        mChildOfContent.getViewTreeObserver().addOnGlobalLayoutListener(
                new ViewTreeObserver.OnGlobalLayoutListener() {
                    public void onGlobalLayout() {
                        possiblyResizeChildOfContent();
                    }
                });
        frameLayoutParams = (FrameLayout.LayoutParams) mChildOfContent
                .getLayoutParams();
    }

    private void possiblyResizeChildOfContent() {
        int usableHeightNow = computeUsableHeight();
        if (usableHeightNow != usableHeightPrevious) {
            int usableHeightSansKeyboard = mChildOfContent.getRootView()
                    .getHeight();
            int heightDifference = usableHeightSansKeyboard - usableHeightNow;
            if (heightDifference > (usableHeightSansKeyboard / 4)) {
// keyboard probably just became visible
                frameLayoutParams.height = usableHeightSansKeyboard
                        - heightDifference;
            } else {
// keyboard probably just became hidden
                frameLayoutParams.height = usableHeightSansKeyboard;
            }
            mChildOfContent.requestLayout();

            usableHeightPrevious = usableHeightNow;
        }
    }
    private int computeUsableHeight() {
        Rect r = new Rect();
        mChildOfContent.getWindowVisibleDisplayFrame(r);
        return (r.bottom - r.top);
    }
// private void showLog(String title, String msg) {
// Log.d("Unity", title + "------------>" + msg);
// }
}

調用方式為：KeyBoardListener.getInstance(this).init();，即可解決全屏下，鍵盤遮擋問題。
