Tips for Android browser Development

My friends and I have made a browser for some time. I will share some tips, write some of them first, write them slowly, and advertisement our browser.

Our browser is coming online, called sofa Browser

1. Right-click menu on the webpage

Public Boolean onlongclick (view) {// gets the clicked element hittestresult mresult = mwebview. gethittestresult (); Final int type = mresult. getType (); Switch (type) {Case hittestresult. anchor_type: Case hittestresult. src_anchor_type: // click the link break; Case hittestresult. image_type: Case hittestresult. image_anchor_type: Case hittestresult. src_image_anchor_type: // The image break is clicked; default: // the blank space break is clicked;} return true ;}

Determine whether the image is an image, link, or blank

2. Free copy on the webpage

Reprinted please indicate the source: http://blog.csdn.net/ethan_xue/article/details/7748075

/*** Copy and paste * @ Param view webview * @ author Ethan */private void emulateshiftheld (keyevent. callback view) {try {keyevent shiftpressevent = new keyevent (0, 0, keyevent. action_down, keyevent. keycode_shift_left, 0, 0); shiftpressevent. dispatch (view);} catch (exception e ){}}

3. Error Page

The error interface provided by WebKit is not domineering enough, so it is changed to an error interface made by myself.

New webviewclient ()... this is the background @ overridepublic void onreceivederror (webview view, int errorcode, string description, string failingurl) {view. stoploading (); view. clearview (); // display the error page mwebview. loadurl ("file: // android_asset/error.html ");}

4. Click an external link to call your browser.

Add intent to the main activity in manifest. xml

<!-- For these schemes were not particular MIME type has been                 supplied, we are a good candidate. -->            <intent-filter>                <action android:name="android.intent.action.VIEW" />                <category android:name="android.intent.category.DEFAULT" />                <category android:name="android.intent.category.BROWSABLE" />                <data android:scheme="http" />                <data android:scheme="https" />                <data android:scheme="about" />                <data android:scheme="javascript" />            </intent-filter>            <!--  For these schemes where any of these particular MIME types                  have been supplied, we are a good candidate. -->            <intent-filter>                <action android:name="android.intent.action.VIEW" />                <category android:name="android.intent.category.BROWSABLE" />                <category android:name="android.intent.category.DEFAULT" />                <data android:scheme="http" />                <data android:scheme="https" />                <data android:scheme="inline" />                <data android:mimeType="text/html"/>                <data android:mimeType="text/plain"/>                <data android:mimeType="application/xhtml+xml"/>                <data android:mimeType="application/vnd.wap.xhtml+xml"/>            </intent-filter>                <action android:name="android.intent.action.VIEW" />                <category android:name="android.intent.category.DEFAULT" />                <category android:name="android.intent.category.BROWSABLE" />                <data android:scheme="file" />            </intent-filter>

The external call is OK, and the file can be called, if you call it yourself

Uri uri = Uri.parse("file://data/data/test.html");//   Uri uri = Uri.parse("http://m.baidu.com");       Intent it = new Intent(Intent.ACTION_VIEW, uri);          context.startActivity(it);
