Android的 - 网页视图页面需要双击 - 如何处理？ [英] Android - Webview page requires double clicking - how to handle?
问题描述
我的应用程序仅仅是为了显示特定网站的WebView。用户不能简单地使用，因为在Android中固有的编程从而改变窃听功能的Chrome应用。
为了简单起见，假设该网站显示日历和该日历上的盒子。这些盒子既可以单单击要选择或单击双击要打开显示事件的详细信息。
该网站有编码处理的事如果事件是单人或双人点击：
＆LT; DIV CLASS =boardpiece点击的onclick =选择（事件，这一点）; onfocus此=打开（'5657849'）;
我用长preSS模拟了双击完全没问题。这里是我的混乱开始的地方。如何我告诉我的应用程序，当用户执行关于该项目的SingleTap，它需要激活的onclick的网站呼吁？我还需要告诉应用程序，当用户执行上同一项长期preSS，激活onfocus此事件您在网站上看到有编码？

我觉得你看这是错误的。相反的检测在Android中双击，并试图将其注入到你的Javascript你可能会被检测在JavaScript中双击。只要保持最后一个阶梯的时候，如果它已经足够最近第二次敲击是双击的一部分。
My app is simply a WebView to display a specific website. Users are not able to simply use the Chrome app because of the inherent programming in Android which alters the functions of tapping.
For simplicity, let's say the website displays a calendar and on that calendar are boxes. The boxes can either be single clicked to be selected or double clicked to be opened to display the event details.
The website has coding that handles what to do if an event is single or double clicked:
<div class="boardpiece clickable" onclick="select(event, this);" ondblclick="open('5657849');"
I'm completely fine with using longpress to simulate the double click. Here's where my confusion begins. How to I tell my app that when the user performs a SingleTap on the item, it needs to activate the "onclick" the website is calling for? I also need to tell the app that when the user performs a longpress on that same item, activate the "ondblclick" event you see there in the website coding?
Here is my activity code:
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.webkit.SslErrorHandler;
import android.net.http.SslError;
import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.GestureDetector;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.GestureDetector.SimpleOnGestureListener;
import android.view.MotionEvent;
public class MainActivity extends Activity{
WebView webview;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webview = (WebView) findViewById(R.id.webview);
//Do we want/need to enable Java?
webview.getSettings().setJavaScriptEnabled(true);
//Here we allow for zoom controls - pinch
webview.getSettings().setBuiltInZoomControls(true);
//Here we remove the zoom control buttons - requires API 11
webview.getSettings().setDisplayZoomControls(false);
//Here we clear the Cache and SSL Preferences
webview.clearCache(true);
webview.clearSslPreferences();
//Do we need to enable scroll bars to allow people to scroll left and right?
webview.setHorizontalScrollBarEnabled(true);
webview.setVerticalScrollBarEnabled(true);
webview.setWebViewClient(new WebViewClient());
webview.loadUrl("https://website");
final GestureDetector gd = new GestureDetector(new MyGestureDetector());
View.OnTouchListener gl = new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
return gd.onTouchEvent(event);
}
};
webview.setOnTouchListener(gl);
}
class MyGestureDetector extends SimpleOnGestureListener {
@Override
public boolean onDoubleTap(MotionEvent e) {
Log.i("", "DoubleTap");
return true;
}
public boolean onSingleTap(MotionEvent e) {
Log.i("", "SingleTap");
return true;
}
}
// Ignore SSL certificate errors
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
handler.proceed();
}
//Would like to have a Menu Button to refresh the page - or really just bring you to the login page - for use when the session times out
@Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(1, 1, 0, "Reload");
//getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()){
case R.id.reload:
webview.loadUrl("website");
return true;
}
return super.onOptionsItemSelected(item);
}
}
I think you're looking at this wrong. Instead of detecting the double tap in Android and trying to inject it into your Javascript you could be detecting the double tap in Javascript. Just keep the time of the last tap and if it's been recently enough the second tap is part of a double tap.
