把键盘抵上去

1.

import android.content.Context;import android.util.AttributeSet;import android.util.Log;import android.widget.RelativeLayout;public class KeyboardLayout extends RelativeLayout {private static final String TAG = KeyboardLayout.class.getSimpleName();public static final byte KEYBOARD_STATE_SHOW = -3;public static final byte KEYBOARD_STATE_HIDE = -2;public static final byte KEYBOARD_STATE_INIT = -1;private boolean mHasInit;private boolean mHasKeybord;private int mHeight;private onKybdsChangeListener mListener;public KeyboardLayout(Context context, AttributeSet attrs, int defStyle) {super(context, attrs, defStyle);}public KeyboardLayout(Context context, AttributeSet attrs) {super(context, attrs);}public KeyboardLayout(Context context) {super(context);}/** * set keyboard state listener */public void setOnkbdStateListener(onKybdsChangeListener listener){mListener = listener;}@Overrideprotected void onLayout(boolean changed, int l, int t, int r, int b) {super.onLayout(changed, l, t, r, b);if (!mHasInit) {mHasInit = true;mHeight = b;if (mListener != null) {mListener.onKeyBoardStateChange(KEYBOARD_STATE_INIT);}} else {mHeight = mHeight < b ? b : mHeight;// ȡ���}if (mHasInit && mHeight > b) {mHasKeybord = true;if (mListener != null) {mListener.onKeyBoardStateChange(KEYBOARD_STATE_SHOW);}Log.w(TAG, "show keyboard.......");}if (mHasInit && mHasKeybord && mHeight == b) {mHasKeybord = false;if (mListener != null) {mListener.onKeyBoardStateChange(KEYBOARD_STATE_HIDE);}Log.w(TAG, "hide keyboard.......");}}public interface onKybdsChangeListener{public void onKeyBoardStateChange(int state);}}

2.

在xml文件下面的布局改成com.handongkeji.widget.KeyboardLayout   给个id     parent

3.在项目里面开始初始化

private KeyboardLayout parent;

4.

实现监听的接口implements onKybdsChangeListener

5.

@Override    public void onKeyBoardStateChange(int state) {                switch (state) {        case KeyboardLayout.KEYBOARD_STATE_SHOW:            break;        case KeyboardLayout.KEYBOARD_STATE_HIDE:                        break;        }        etlastAddress.addOnLayoutChangeListener(new OnLayoutChangeListener() {            @Override            public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {                scrollview.smoothScrollBy(0, etlastAddress.getHeight());            }        });          }
