comment rechercher du texte dans webview

Alors que c'est une vieille question, basée sur AndroidEnthusiastic la version que j'ai réussi à mettre ensemble celui qui était réellement travail assez décent. Il y a une petite erreur avec le type de bouton sur le Samsung Note je l'ai testé, mais pas n'importe comment, j'ai changé l'IME types, il a juste obtenu foiré. Donc, je suis juste de cacher les touches de clavier. Mais la mise en page est mieux construit.

public class SearchDemoActivity extends ActionBarActivity implements View.OnClickListener
{
WebView mWebView;
private RelativeLayout container;
private Button nextButton, closeButton;
private EditText findBox;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search);
getActionBar().setTitle(R.string.information_display);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.setWebViewClient(new WebViewClient());
mWebView.loadUrl("http://devemat-androidprogramming.blogspot.com/");
nextButton = (Button) findViewById(R.id.nextButton);
closeButton = (Button) findViewById(R.id.closeButton);
findBox = (EditText) findViewById(R.id.findBox);
findBox.setSingleLine(true);
findBox.setOnKeyListener(new OnKeyListener()
{
public boolean onKey(View v, int keyCode, KeyEvent event)
{
if ((event.getAction() == KeyEvent.ACTION_DOWN) && ((keyCode == KeyEvent.KEYCODE_ENTER)))
{
mWebView.findAll(findBox.getText().toString());
try
{
//Can't use getMethod() as it's a private method
for (Method m : WebView.class.getDeclaredMethods())
{
if (m.getName().equals("setFindIsUp"))
{
m.setAccessible(true);
m.invoke(mWebView, true);
break;
}
}
}
catch (Exception ignored)
{
}
finally
{
InputMethodManager inputManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
//check if no view has focus:
View vv = getCurrentFocus();
if (vv != null)
{
inputManager.hideSoftInputFromWindow(v.getWindowToken(),
InputMethodManager.HIDE_NOT_ALWAYS);
}
}
}
return false;
}
});
nextButton.setOnClickListener(this);
closeButton.setOnClickListener(this);
}
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
super.onCreateOptionsMenu(menu);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.searchview_in_menu, menu);
return true;
}
public boolean onPrepareOptionsMenu(Menu menu)
{
super.onPrepareOptionsMenu(menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.action_search:
search();
return true;
}
return true;
}
public void search()
{
container = (RelativeLayout) findViewById(R.id.layoutId);
if (container.getVisibility() == RelativeLayout.GONE)
{
container.setVisibility(RelativeLayout.VISIBLE);
}
else if (container.getVisibility() == RelativeLayout.VISIBLE)
{
container.setVisibility(RelativeLayout.GONE);
}
}
@Override
public void onClick(View v)
{
if (v == nextButton)
{
mWebView.findNext(true);
}
else if (v == closeButton)
{
container.setVisibility(RelativeLayout.GONE);
}
}
}

La mise en page XML (activity_search.xml):

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<WebView
android:id="@+id/webview"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_below="@+id/layoutId" />
<RelativeLayout
android:id="@+id/layoutId"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:visibility="gone" >
<Button
android:id="@+id/closeButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="Close" />
<Button
android:id="@+id/nextButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="@+id/closeButton"
android:text="Next" />
<EditText
android:id="@+id/findBox"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="@+id/nextButton"
android:hint="Enter search keyword here."
android:singleLine="true" />
</RelativeLayout>
</RelativeLayout>

Le menu:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto" >
<item
android:id="@+id/action_search"
android:icon="@android:drawable/ic_menu_search"
custom:showAsAction="always"
android:title="@string/action_search"/>
</menu>

De vérifier en permanence le texte de WebView utiliser ce code:

webView.setFindListener(new WebView.FindListener() {
@Override
public void onFindResultReceived(int activeMatchOrdinal, int numberOfMatches, boolean isDoneCounting) {
webView.findAllAsync("Search Text"); //find text for each foundresult
}
});
