Android软键盘弹出和隐藏事件监听Demo源代码下载

想实现软键盘的监听、我们必须要自定义View来实现、因为系统提供的状态判断返回值一直是true、无法使用、本Demo利用自定义布局来进行监听、原理是输入法打开时、会对布局造成挤压、这时会调用onLayout方法、因此可以在onLayout中进行判断、运行效果如下

核心代码

public void setOnkeyboarddStateListener(
	onKeyboardsChangeListener listener) {
	keyboarddsChangeListener = listener;
}

// 布局状态发生改变时，会触发onLayout
@Override
protected void onLayout(boolean changed, 
	int l, int t, int r, int b) {
	super.onLayout(changed, l, t, r, b);
	if (!isInit) {
		isInit = true;
		viewHeight = b;
		keyboardSateChange(KEYBOARD_STATE_INIT);
	} else {
		viewHeight = viewHeight < b ? b : viewHeight;
	}
	if (isInit && viewHeight > b) {
		hasKeybord = true;
		keyboardSateChange(KEYBOARD_STATE_SHOW);
		Log.w(TAG, "显示软键盘");
	}
	if (isInit && hasKeybord && viewHeight == b) {
		hasKeybord = false;
		keyboardSateChange(KEYBOARD_STATE_HIDE);
		Log.w(TAG, "隐藏软键盘");
	}
}

//切换软键盘状态
public void keyboardSateChange(int state) {
	if (keyboarddsChangeListener != null) {
		keyboarddsChangeListener.onKeyBoardStateChange(state);
	}
}

//软键盘状态切换监听
public interface onKeyboardsChangeListener {
	public void onKeyBoardStateChange(int state);
}

最后将源代码分享给大家、希望对大家有帮助
