У меня есть PopupWindow, который отображает WebView при нажатии кнопки. Если для setBuiltInZoomControls установлено значение false, WebView отобразит страницу, как ожидалось. Однако если setBuiltInZoomControls установлен в true, любое взаимодействие с WebView (прокрутка, масштабирование) вызывает ошибку.setBuiltInZoomControls с WebView внутри PopupWindow
Вот Java код:
mHelpButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
LayoutInflater inflater = (LayoutInflater) getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = inflater.inflate(R.layout.help_pop, null);
int width = WindowManager.LayoutParams.MATCH_PARENT;
int height = WindowManager.LayoutParams.WRAP_CONTENT;
final PopupWindow popupWindow = new PopupWindow(popupView, 1, 1, true);
popupWindow.setWindowLayoutMode(width,height);
popupWindow.setOutsideTouchable(true);
popupWindow.setBackgroundDrawable(new BitmapDrawable(getResources(), ""));
TextView helpText = (TextView) popupView.findViewById(R.id.help_text);
WebView webView = (WebView)popupView.findViewById(R.id.app_question_help_web_view);
if (!mQuestion.casiHelpText.contains("http://") && !mQuestion.casiHelpText.contains("<")) {
helpText.setText(mQuestion.casiHelpText);
popupWindow.showAsDropDown(mHelpButton);
} else if (mQuestion.casiHelpText.contains("http://") && !mQuestion.casiHelpText.contains("<")) {
if ((getResources().getConfiguration().screenLayout &
Configuration.SCREENLAYOUT_SIZE_MASK) ==
Configuration.SCREENLAYOUT_SIZE_XLARGE) {
Log.d(TAG,"Large size screen targeted");
webView.setVisibility(View.VISIBLE);
helpText.setVisibility(View.GONE);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.loadUrl(mQuestion.casiHelpText);
findViewById(R.id.app_questions_activity_layout).post(new Runnable() {
public void run() {
popupWindow.showAsDropDown(mHelpButton);
}
});
}
else {
Intent i = new Intent(QuestionsActivity.this, WebViewActivity.class);
i.setData(Uri.parse(mQuestion.casiHelpText));
startActivity(i);
}
} else {
if ((getResources().getConfiguration().screenLayout &
Configuration.SCREENLAYOUT_SIZE_MASK) ==
Configuration.SCREENLAYOUT_SIZE_XLARGE) {
webView.setVisibility(View.VISIBLE);
helpText.setVisibility(View.GONE);
String baseHtml = "<html><meta name=\"viewport\" content=\"width=200\"/><head><title></title></head><body>" + mQuestion.casiHelpText + "</body><html>";
webView.loadDataWithBaseURL(null, baseHtml, "text/html", "UTF-8", null);
popupWindow.showAsDropDown(mHelpButton);
webView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
});
} else {
Intent i = new Intent(QuestionsActivity.this, WebViewActivity.class);
i.putExtra("HTML", mQuestion.casiHelpText);
startActivity(i);
}
}
}
});
Вот мой layout.xml (sw600dp). Просто содержит WebView и TextView
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
android:gravity="center"
android:background="@android:color/darker_gray">
<WebView
android:id="@+id/app_question_help_web_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@android:color/white"
android:visibility="gone"/>
<TextView
android:id="@+id/help_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="testestestetstetst"
android:textColor="@android:color/white"
android:layout_below="@+id/app_question_help_web_view"
/>
