Example 1 Of Parse HTML File content Using WebView With Example In Android Studio:

Below is the example of HTML in which we parse the HTML file and display the HTML content in our Android WebView. In this example firstly we create a assets folder and store a HTML file in it. After that we create a WebView in our XML file and then get the reference of WebView in our MainActivity and finally with the help of loadUrl() method we display the content in our webView.

Step 1: Create a new project and name it HtmlExample.

Step 2: Open res -> layout -> activity_main.xml (or) main.xml and add following code:

In this step we open an xml file and add the code for displaying a WebView.

Step 3: Now create assets folder in App. You can read here how to create assets folder in Android Studio

Step 4: Now inside assets folder add a HTML file name myfile.html. You can read here how to add local html file in Android Studio. Also inside myfile.html add the below HTML content or add any content in HTML format.

Step 5: Now Open src -> package -> MainActivity.java

In this step we open MainActivity where we add the code to initiate the WebView and then display the HTML content from file stored in assets folder into WebView.

package abhiandroid.com.htmlexample; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.webkit.WebView; public class MainActivity extends AppCompatActivity < WebView webView; public String fileName = "myfile.html"; @Override protected void onCreate(Bundle savedInstanceState) < super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // init webView webView = (WebView) findViewById(R.id.simpleWebView); // displaying content in WebView from html file that stored in assets folder webView.getSettings().setJavaScriptEnabled(true); webView.loadUrl("file:///android_asset/" + fileName); >>

Now run the App and you will see local content added in HTML file is loaded in Webview.

Example 2 Of HTML In Android Studio Using TextView:

Below is the example of HTML in which we display the HTML content in our Android TextView with the help of fromHtml() method. In this example firstly we create a TextView in our XML file and then get the reference of TextView in our MainActivity and finally with the help of fromHtml() method we set the content in our TextView.

Step 1: Create a new project and name it HtmlExample.

Step 2: Open res -> layout -> activity_main.xml (or) main.xml and add following code:

In this step we open an xml file and add the code for displaying a TextView.

Step 3: Now Open src -> package -> MainActivity.java

In this step we open MainActivity where we add the code to initiate the TextView and then set the HTML content which is stored in a string variable into TextView using fromHtml() method.

\n» + «
• One\n» + «
• Two\n» + «
• Three\n» + «

\n» + «
1. One\n» + «
2. Two\n» + «
3. Three\n» + «

Now run the App and you will see HTML content is shown in TextView.

Example 3 Of HTML content in WebView With Example in Android Studio:

Below is the example of HTML in which we display the HTML content in our Android WebView. In this example firstly we create a WebView in our XML file and then get the reference of WebView in our MainActivity and finally with the help of loadDataWithBaseURL() method we display the content in our webView.

Step 1: Create a new project and name it HtmlWebViewExample.

Step 2: Open res -> layout -> activity_main.xml (or) main.xml and add following code:

In this step we open an xml file and add the code for displaying a WebView.

Step 3: Now Open src -> package -> MainActivity.java

In this step we open MainActivity where we add the code to initiate the WebView and then display the HTML content which is stored in a string variable into WebView.

\n» + «
• One\n» + «
• Two\n» + «
• Three\n» + «

\n» + «
1. One\n» + «
2. Two\n» + «
3. Three\n» + «

Now run the App and you will see HTML content is displayed using Webview.
