Android 在webview上缩放不起作用

Android 在webview上缩放不起作用,android,android-webview,Android,Android Webview,当onTouchEvent发现zoom不工作时,我有一个扩展webview的类 @Override public boolean onTouchEvent(MotionEvent event) { super.cancelLongPress(); int action = event.getAction(); if (action == MotionEvent.ACTION_DOWN || action == MotionEvent.ACTION_

当onTouchEvent发现zoom不工作时,我有一个扩展webview的类

@Override
public boolean onTouchEvent(MotionEvent event) {
    super.cancelLongPress();
    int action = event.getAction();
    if (action == MotionEvent.ACTION_DOWN
            || action == MotionEvent.ACTION_UP) {
        super.onTouchEvent(event);
    } else if (action == MotionEvent.ACTION_CANCEL
            || action == MotionEvent.ACTION_MOVE) {
        MotionEvent e = MotionEvent.obtain(event);
        e.setAction(MotionEvent.ACTION_CANCEL);
        super.onTouchEvent(e);
    }

    gestureDetector.onTouchEvent(event);
    super.cancelLongPress();
    return true;
}
使用以下命令: 再加上

wv.getSettings().setSupportZoom(true);
wv.getSettings().setBuiltInZoomControls(true);

现在试试我的答案。两者相加
