在android中单击EditText外部时关闭键盘

Question

我有一个EditText电话myTextview.我希望软键盘在我点击时显示,EditText但如果我点击外面则解雇EditText.所以我使用下面的方法.但是当我在视图外面点击时键盘不会被忽略(我点击了一下TextView).我该如何修复此代码？

myTextview.setOnFocusChangeListener(new OnFocusChangeListener() {

        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {
                getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
            } else {
                InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(myTextview.getWindowToken(), 0);
            }

        }
    });

我找到了更好的解决方案:

覆盖dispatchTouchEventActivity中的方法.

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    View v = getCurrentFocus();

    if (v != null && 
            (ev.getAction() == MotionEvent.ACTION_UP || ev.getAction() == MotionEvent.ACTION_MOVE) && 
            v instanceof EditText && 
            !v.getClass().getName().startsWith("android.webkit.")) {
        int scrcoords[] = new int[2];
        v.getLocationOnScreen(scrcoords);
        float x = ev.getRawX() + v.getLeft() - scrcoords[0];
        float y = ev.getRawY() + v.getTop() - scrcoords[1];

        if (x < v.getLeft() || x > v.getRight() || y < v.getTop() || y > v.getBottom())
            hideKeyboard(this);
    }
    return super.dispatchTouchEvent(ev);
}

public static void hideKeyboard(Activity activity) {
    if (activity != null && activity.getWindow() != null && activity.getWindow().getDecorView() != null) {
        InputMethodManager imm = (InputMethodManager)activity.getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(activity.getWindow().getDecorView().getWindowToken(), 0);
    }
}

即使您正在使用webview,这也适用.

也许有点容易:

在编辑文本上设置focusChangedListener,然后在没有焦点时隐藏键盘.

yourEditText.setOnFocusChangeListener(new OnFocusChangeListener() {

    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if(!hasFocus){
            hideKeyboard();
        }               
    }
});

private void hideKeyboard() {
    InputMethodManager imm = (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(yourEditText.getWindowToken(), 0);
}

这样，只有当您触摸可以获得焦点的视图时，键盘才会消失。我建议您执行以下操作：

像这样创建一个自定义 ViewGroup：

public class TouchLayout extends LinearLayout {

    private OnInterceptTouchEventListener mListener;

    public TouchLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        if(mListener != null) {
            return mListener.onInterceptTouchEvent(event);
        }
        return super.onInterceptTouchEvent(event);
    }

    public void setOnInterceptTouchEventListener(OnInterceptTouchEventListener listener) {
        mListener = listener;
    }

    public interface OnInterceptTouchEventListener {
        public boolean onInterceptTouchEvent(MotionEvent event);
    }
}

然后将自定义视图添加为 xml 布局的根：

<com.example.TouchLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/root"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

        <EditText
            android:id="@+id/text"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

在您的 Activity 中您应该执行以下操作：

final TouchLayout root = (TouchLayout) findViewById(R.id.root);
final EditText text = (EditText) findViewById(R.id.text);
final InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

root.setOnInterceptTouchEventListener(new OnInterceptTouchEventListener() {

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        final View v = getCurrentFocus();
        if(v != null && v.equals(text)) {
            final int screenCords[] = new int[2];
            text.getLocationOnScreen(screenCords);
            final Rect textRect = new Rect(screenCords[0], screenCords[1], screenCords[0] + text.getWidth(), screenCords[1] + text.getHeight());
            if(!textRect.contains(event.getRawX(), event.getRawY() {
                imm.hideSoftInputFromWindow(myTextview.getWindowToken(), 0);
                // Optionally you can also do the following:
                text.setCursorVisible(false);
                text.clearFocus(); 
            }
        }
        return false;
    }
};
