使用步骤

xml 布局文件布局，和普通的控件一下

获取SoftInputCanListenerEditText 实例，并设置监听器

Activity 注册的时候android:windowSoftInputMode 使用默认值，就是说不要写这个就对了

/**

public class SoftInputCanListenerEditText extends AppCompatEditText {

private OnSoftInputChangeListener mOnSoftInputChangeListener;

private int mPreHeight; //上一次计算时的高度

private View mContentView;

private boolean isShow;

public SoftInputCanListenerEditText(Context context) {

super(context);

}

public SoftInputCanListenerEditText(Context context, AttributeSet attrs) {

super(context, attrs);

}

public SoftInputCanListenerEditText(Context context, AttributeSet attrs, int defStyleAttr) {

super(context, attrs, defStyleAttr);

}

public void setOnSoftInputChangeListener(OnSoftInputChangeListener onSoftInputChangeListener) {

mOnSoftInputChangeListener = onSoftInputChangeListener;

}

@Override

protected void onDraw(Canvas canvas) {

super.onDraw(canvas);

if (isInEditMode()) {

return;

}

if (mContentView == null) {

Activity activity = (Activity) ((TintContextWrapper) getContext()).getBaseContext();

mContentView = activity.findViewById(android.R.id.content);

}

int nowHeight = mContentView.getHeight();

if (mPreHeight == 0) {

//第一次进入

mPreHeight = nowHeight;

return;

}

if (mPreHeight == nowHeight) {

//同样的不处理

return;

}

if (mOnSoftInputChangeListener != null && nowHeight < mPreHeight) {

//变小了之后就是显示了键盘

mOnSoftInputChangeListener.onChange(true);

isShow = true;

//显示键盘之后就开始检查什么时候收起

startCheck();

mPreHeight = nowHeight;

}

}

private Runnable check = () -> {

int nowHeight = mContentView.getHeight();

if (mOnSoftInputChangeListener != null && nowHeight > mPreHeight) {

//变小了之后就是显示了键盘

mOnSoftInputChangeListener.onChange(false);

isShow = false;

mPreHeight = nowHeight;

return;

}

//键盘没有收起，接着检查

startCheck();

};

//定时检查才行呀

private void startCheck() {

postDelayed(check, 100);

}

public boolean isShow() {

return isShow;

}

public interface OnSoftInputChangeListener{

void onChange(boolean isShow);

}

}

感谢支持，更多请看把时间当初朋友
