如何使用adjustPan保持工具栏可见？

Question

我有一个如下布局，当用户点击EditText时，我希望有以下行为：

< li >键盘应该覆盖“底部对齐的LinearLayout < li>EditText应该在屏幕上可见，而不是被键盘覆盖。 < li >工具栏应该在屏幕上可见；

未满足的要求:

未满足的要求:

1. 键盘应该覆盖“与底部对齐的LinearLayout”；

未满足的要求:

是否有人遇到过同样的问题并达到了要求？

Answer 1

将父布局更改为相对布局

public class SizeNotifierRelativeLayout extends RelativeLayout {

private Rect rect = new Rect();
public SizeNotifierRelativeLayoutDelegate delegate;

public abstract interface SizeNotifierRelativeLayoutDelegate {
    public abstract void onSizeChanged(int keyboardHeight);
}

public SizeNotifierRelativeLayout(Context context) {
    super(context);
}

public SizeNotifierRelativeLayout(android.content.Context context, android.util.AttributeSet attrs) {
    super(context, attrs);
}

public SizeNotifierRelativeLayout(android.content.Context context, android.util.AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}


/**
 * Calculate the soft keyboard height and report back to listener
 * @param changed
 * @param l
 * @param t
 * @param r
 * @param b
 */
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
    super.onLayout(changed, l, t, r, b);
    if (delegate != null) {
        View rootView = this.getRootView();
        int usableViewHeight = rootView.getHeight() - AndroidUtilities.statusBarHeight - AndroidUtilities.getViewInset(rootView);
        this.getWindowVisibleDisplayFrame(rect);
        int keyboardHeight = usableViewHeight - (rect.bottom - rect.top);
        delegate.onSizeChanged(keyboardHeight);
    }
}

接下来，在您的活动或片段中包含这些代码

 private SizeNotifierRelativeLayout sizeNotifierRelativeLayout;
  View rootView;


       @Override
            public void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);

          rootView = view.findViewById(R.id.root);
          sizeNotifierRelativeLayout = (SizeNotifierRelativeLayout) 
                                        view.findViewById(R.id.chat_layout);
                sizeNotifierRelativeLayout.delegate = this;


  rootView.getViewTreeObserver().addOnGlobalLayoutListener(new 
  ViewTreeObserver.OnGlobalLayoutListener() {
                @Override
                public void onGlobalLayout() {

                    Rect r = new Rect();
                    rootView.getWindowVisibleDisplayFrame(r);
                    int screenHeight = rootView.getRootView().getHeight();


                    int keypadHeight = screenHeight - r.bottom;

                    Log.d("Height", "keypadHeight = " + keypadHeight);

                    if (keypadHeight > screenHeight * 0.15) { // 0.15 ratio is perhaps enough to determine keypad height.
                        // keyboard is opened
                        if (sizeNotifierRelativeLayout != null) {
                            sizeNotifierRelativeLayout.setPadding(0, 0, 0, keypadHeight - 200);
                        }
                    } else {
                        // keyboard is closed
                        if (sizeNotifierRelativeLayout != null) {
                            sizeNotifierRelativeLayout.post(new Runnable() {
                                public void run() {
                                    if (sizeNotifierRelativeLayout != null) {
                                        sizeNotifierRelativeLayout.setPadding(0, 0, 0, 0);
                                    }
                                }
                            });
                        }
                        try {

                            }
                        } catch (NullPointerException e) {
                            e.printStackTrace();
                            System.out.print(e.getMessage());
                        }
                    }
                }
            });


            }

Answer 2

我认为没有非常简单的方法来实现这一点。但这里有一个项目，它有一个SizeNotifierRelativeLayout，然后在键盘打开时弹出。

Answer 3

我不确定是否有任何开箱即用的解决方案可以让它按照您的预期工作。

但是，您可以通过使用＜code＞WindowsOfInputMode=adjustNothing

如果不清楚如何实现滚动，我可以添加一个例子。
