Source: //developer.android.com/resources/browser.html?tag=sample
License: //www.apache.org/licenses/LICENSE-2.0
1.) Automatically linkifies using android:autoLink="all"
// res/values/strings.xml
<string name="link_text_auto"><b>text1:</b> This is some text. In
this text are some things that are actionable. For instance,
you can click on //www.google.com and it will launch the
web browser. You can click on google.com too. And, if you
click on (415) 555-1212 it should dial the phone.
</string>
// main.xml
<!-- text1 automatically linkifies things like URLs and phone numbers. -->
<TextView xmlns:android="//schemas.android.com/apk/res/android"
android:id="@+id/text1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:autoLink="all"
android:text="@string/link_text_auto"
/>
2.) Link text by setMovementMethod
// MainActivity.java onCreate
/*Be warned that if you want a TextView with a key listener or movement method not to be focusable, or if you want a TextView without a key listener or movement method to be focusable, you must call setFocusable(boolean) again after calling this to get the focusability back the way you want it. */
TextView t2 = (TextView) findViewById(R.id.text2);
t2.setMovementMethod(LinkMovementMethod.getInstance());
// main.xml
<!-- text2 uses a string resource containing explicit <a> tags to
specify links. -->
<TextView xmlns:android="//schemas.android.com/apk/res/android"
android:id="@+id/text2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="@string/link_text_manual"
/>
//strings.xml
<string name="link_text_manual"><b>text2:</b> This is some other
text, with a <a href="//www.google.com">link</a> specified
via an <a> tag. Use a \"tel:\" URL
to <a href="tel:4155551212">dial a phone number</a>.
</string>
3.) Link as html code using Html.fromHtml()
// MainActivity.java onCreate
TextView t3 = (TextView) findViewById(R.id.text3);
t3.setText(
Html.fromHtml(
"<b>text3:</b> Text with a " +
"<a href=\"//www.google.com\">link</a> " +
"created in the Java source code using HTML."));
t3.setMovementMethod(LinkMovementMethod.getInstance());
4.) Link string by SpannableString
SpannableString ss = new SpannableString(
"text4: Click here to dial the phone.");
ss.setSpan(new StyleSpan(Typeface.BOLD), 0, 6,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
ss.setSpan(new URLSpan("tel:4155551212"), 13, 17,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
TextView t4 = (TextView) findViewById(R.id.text4);
t4.setText(ss);
t4.setMovementMethod(LinkMovementMethod.getInstance());

public class Main extends Activity {
private TextView mTextView;
private Activity mAct;
private Intent mIntent;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_layout);
mTextView = findViewById(R.id.mTextView);
mAct = getActivity();
mIntent = getIntent();
}
}
to:
public class Main extends Fragment{
private TextView mTextView;
private FragmentActivity mFrgAct;
private Intent mIntent;
private LinearLayout mLinearLayout;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.fragment_main, null);
return root;
}
public void onViewCreated(View view, Bundle savedInstanceState) {
// you can add listener of elements here
/*Button mButton = (Button) view.findViewById(R.id.button);
mButton.setOnClickListener(this); */
mTextView = view.findViewById(R.id.mTextView);
mLinearLayout = (LinearLayout)view;
}
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
mFrgAct = getActivity();
mIntent = mFrgAct.getIntent(); // Intent intent = new Intent(getActivity().getIntent());
}
}
Problem: erroneous entry of id
Solution: @+id/
<RadioButton android:id="idRadio"
android:text="My radio button"/>
Solution: @+id/
<RadioButton android:id="@+id/idRadio"
android:text="My radio button"/>
float, double is NaN isNaN() isInfinite() Java Android example.
float f = 0.f;
boolean bIsNaN = Float.isNaN(f);
boolean bIsInfinite = Float.isInfinite(f);
double d = Math.sqrt(-10);
boolean b = Double.isNaN(d);
onCreate in MainActivity.java
You can add to titlebar different Views by xml file.
custom_title.xml

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.main.xml);
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.custom_title);
}
You can add to titlebar different Views by xml file.
custom_title.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="//schemas.android.com/apk/res/android" android:id="@+id/screen"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:orientation="vertical">
<TextView android:id="@+id/left_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="Some text" />
<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:src="@drawable/ic_launcher" />
