android软键盘弹出隐藏的监听

通过网上搜索关于软键盘的隐藏弹出的监听，有几种方式，其中最有效的方式是在View的Onlayout（）里面做文章

具体代码：

将布局视图自定义，重写onlayout()方法，然后在主Activity里面调用接口就可以了

/**
 * 为了监听软键盘的弹出隐藏
 * 
 */
public class ResizeLayout extends LinearLayout {
	private InputListener mListener;
	
	public interface InputListener {
		void OnInputListener(boolean isHideInput);
	}
	
	public void setOnResizeListener(InputListener l) {
		mListener = l;
	}
	
	public ResizeLayout(Context context, AttributeSet attrs) {
		super(context, attrs);
	}
	
	private boolean mHasInit = false;
	private boolean mHasKeyboard = false;
	private int mHeight;
	
	@Override
	protected void onLayout(boolean changed, int l, int t, int r, int b) {
		// TODO Auto-generated method stub
		super.onLayout(changed, l, t, r, b);
		if (!mHasInit) {
			mHasInit = true;
			mHeight = b;
			System.out.println("mHeight= " + b);
		}
		else {
			mHeight = mHeight < b ? b : mHeight;
		}
		
		if (mHasInit && mHeight > b) { // mHeight代表键盘的真实高度 ,b代表在窗口中的高度 mHeight>b
			mHasKeyboard = true;
			mListener.OnInputListener(false);
		}
		if (mHasInit && mHasKeyboard && mHeight == b) { // mHeight = b
			mHasKeyboard = false;
			mListener.OnInputListener(true);
		}
	}
