Application stops working

At first I try this way . And I get stuck then, I ask a question, but no one gives any answer. Then I will try another method suggested by @ sayed.jalil in this link . But my application stops working. If someone provides an answer for the first link. And if someone wants to answer the alternative, I tried according to @ sayed.jalil's answer. For this, my code below is

Xml code -

<com.info.abc.JustifiedTextView android:id="@+id/textview1" android:textColor="#FFFFFF"/>

Operation code -

 JustifiedTextView txtViewEx = (JustifiedTextView) findViewById(R.id.textview1); txtViewEx.setText("some text");

JustifiedTextView.java -

 import android.annotation.SuppressLint; import android.content.Context; import android.graphics.Color; import android.text.SpannableString; import android.webkit.WebChromeClient; import android.webkit.WebView; public class JustifiedTextView extends WebView { private String core = "<html><body style='text-align:justify;color:rgba(%s);font-size:%dpx;margin: 10px 10px 10px 10px;'>%s</body></html>"; private String textColor = "0,0,0,255"; private String text = ""; private int textSize = 12; private int backgroundColor = Color.TRANSPARENT; public JustifiedTextView(Context context) { super(context); this.setWebChromeClient(new WebChromeClient() { }); } public void setText(String s) { this.text = s; // this.setPadding(10, 10, 10, 10); reloadData(); } @SuppressLint("NewApi") private void reloadData() { // loadData(...) has a bug showing utf-8 correctly. That why we need // to set it first. this.getSettings().setDefaultTextEncodingName("utf-8"); this.loadData(String.format(core, textColor, textSize, text), "text/html", "utf-8"); // set WebView background color *after* data was loaded. super.setBackgroundColor(backgroundColor); // Hardware rendering breaks background color to work as expected. // Need to use software renderer in that case. if (android.os.Build.VERSION.SDK_INT >= 11) this.setLayerType(WebView.LAYER_TYPE_SOFTWARE, null); } public void setTextColor(int hex) { String h = Integer.toHexString(hex); int a = Integer.parseInt(h.substring(0, 2), 16); int r = Integer.parseInt(h.substring(2, 4), 16); int g = Integer.parseInt(h.substring(4, 6), 16); int b = Integer.parseInt(h.substring(6, 8), 16); textColor = String.format("%d,%d,%d,%d", r, g, b, a); reloadData(); } public void setBackgroundColor(int hex) { backgroundColor = hex; reloadData(); } public void setTextSize(int textSize) { this.textSize = textSize; reloadData(); } }

 Caused by: java.lang.NoSuchMethodException: <init> [class android.content.Context, interface android.util.AttributeSet] 01-19 10:43:19.400: E/AndroidRuntime(1482): at java.lang.Class.getConstructorOrMethod(Class.java:472)

You do not provide all the constructors needed for a custom view.
In particular, add this constructor. Read the documentation and guidelines for using the attribute set:

 public JustifiedTextView(Context context, AttributeSet attrs){ super(context, attrs); this.setWebChromeClient(new WebChromeClient() { }); }
