Question

我最接近的是：

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT)
    {
        InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        inputMethodManager.hideSoftInputFromWindow(input.getWindowToken(), 0);
    }
    //Some other code
}

但这并不奏效。在这种情况下，即使没有输入具有焦点，一旦方向更改为肖像，键盘将被拉起。

使用此util侦听器代码

import android.app.Activity;
import android.view.View;
import android.view.ViewTreeObserver.OnGlobalLayoutListener;

public class KeyboardUtil implements OnGlobalLayoutListener {
static public interface KeyboardListener {
    public void onKeyboardVisible(boolean visible);
}

private int mHeight;
private boolean mVisible;
private View mRootView;
private KeyboardListener mListener;

public KeyboardUtil(Activity activity) {
    mVisible = false;
    mHeight = 0;
    if (activity == null) {
        return;
    }
    try {
        mRootView = activity.getWindow().getDecorView()
                .findViewById(android.R.id.content);
        mRootView.getViewTreeObserver().addOnGlobalLayoutListener(this);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

public void setListener(KeyboardListener listener) {
    this.mListener = listener;
}

@Override
public void onGlobalLayout() {
    if (mHeight == 0) {
        mHeight = mRootView.getMeasuredHeight();
        return;
    }

    if (mListener == null) {
        return;
    }

    int height = mRootView.getHeight();

    if (!mVisible && mHeight > (height + 100)) {
        mVisible = true;
        mListener.onKeyboardVisible(mVisible);
        mHeight = height;
    } else if (mVisible && mHeight < (height - 100)) {
        mVisible = false;
        mListener.onKeyboardVisible(mVisible);
        mHeight = height;
    }
}
}

以下代码用于您的活动

new KeyboardUtil(context).setListener(keyboardListener);

KeyboardUtil.KeyboardListener keyboardListener = new KeyboardUtil.KeyboardListener() {
    @Override
    public void onKeyboardVisible(boolean visible) {
     // get configuration here and 
     if(config is portrait)
         hideSoftKeyboard(this); // Provide you activity context
    }
};

public static void hideSoftKeyboard(Activity activity) {
    InputMethodManager inputMethodManager = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
    inputMethodManager.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), 0);
}

试试这个

View view = this.getCurrentFocus（）;

        try {
            if (view != null) {
                InputMethodManager inputManager = (InputMethodManager) this.getSystemService(Context.INPUT_METHOD_SERVICE);
                inputManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

方向设置为纵向时隐藏键盘
