Create TextView dynamically Android sample

Fill the entire canvas with the specified color.

@Override
    public void onDraw(Canvas canvas) {
    canvas.drawColor(Color.GREEN);
}

SeekBar setOnSeekBarChangeListener Example. Change TextView font size by SeekBar Example.

        TextView mTextView01 = (TextView)findViewById(R.id.textView01);

        SeekBar  mSeekBarTexSize = (SeekBar)findViewById(R.id.seekBarTextSize);
        mSeekBarTexSize.setMax(100);
        mSeekBarTexSize.setProgress(25);

        mSeekBarTexSize.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            public void onProgressChanged(SeekBar seekBar, int progress,
                    boolean fromUser) {
            	mTextView01.setTextSize((float)progress);
            }

            public void onStartTrackingTouch(SeekBar seekBar) {}
            public void onStopTrackingTouch(SeekBar seekBar) {}
        });

build.gradle in module have higher priority then AndrodiManifest.xml
Try this.
AndroidManifest.xml have code:

    <uses-sdk
        android:minSdkVersion="9"
        android:targetSdkVersion="23" />

build.gradle have code:

   defaultConfig {
        applicationId "cz.okhelp.words"
        minSdkVersion 9
        targetSdkVersion 19
        versionCode 107
        versionName "1.0.7"
    }

Warning in AndroidManifest.xml:
This targetSdkVersion value (23) is not used; it is always overridden by the value specified in the Gradle build script (19) less... (Ctrl+F1)
The value of (for example) minSdkVersion is only used if it is not specified in the build.gradle build scripts. When specified in the Gradle build scripts, the manifest value is ignored and can be misleading, so should be removed to avoid ambiguity.

If you change the package name, you have to add new package name in:

DictionaryProvider.java

public class DictionaryProvider extends ContentProvider {
    String TAG = "DictionaryProvider";

//    public static String AUTHORITY = "com.example.android.searchabledict.DictionaryProvider";
// change to your new package name
public static String AUTHORITY = "com.myweb.mysubdomen.searchabledict.DictionaryProvider";
    public static final Uri CONTENT_URI = Uri.parse("content://" + AUTHORITY + "/dictionary");


// in AndroidManifest.xml
//change com.example.android to your package e.g. com.myweb.mysubdomen
<!-- Provides search suggestions for words and their definitions. -->
        <provider android:name="com.example.android.searchabledict.DictionaryProvider"
            android:configChanges="keyboard|keyboardHidden|orientation"
                  android:authorities="com.example.android.searchabledict.DictionaryProvider" />

        <!-- Points to searchable activity so the whole app can invoke search. -->
        <meta-data android:name="android.app.default_searchable"
            android:configChanges="keyboard|keyboardHidden|orientation"
                   android:value=".SearchableDictionary" />

// I change like this:
        <!-- Provides search suggestions for words and their definitions. -->
        <provider android:name=".DictionaryProvider"
            android:configChanges="keyboard|keyboardHidden|orientation"
                  android:authorities="cz.okhelp.android.searchabledict.DictionaryProvider" />

        <!-- Points to searchable activity so the whole app can invoke search. -->
        <meta-data android:name="android.app.default_searchable"
            android:configChanges="keyboard|keyboardHidden|orientation"
                   android:value=".SearchableDictionary" />

Do not forget change package name in all java class and xml/searchable.xml
In my project I changed like this:

<searchable xmlns:android="//schemas.android.com/apk/res/android"
        android:label="@string/search_label"
        android:hint="@string/search_hint"
        android:searchSettingsDescription="@string/settings_description"
        android:searchSuggestAuthority="cz.okhelp.android.searchabledict.DictionaryProvider"
        android:searchSuggestIntentAction="android.intent.action.VIEW"
        android:searchSuggestIntentData="content://cz.okhelp.android.searchabledict.DictionaryProvider/dictionary"
        android:searchSuggestSelection=" ?"
        android:searchSuggestThreshold="1"
        android:includeInGlobalSearch="true"
        >
 </searchable>

Android development

long is 64 bit signed type and used when int is not large enough to hold the value.

long je celé číslo 64 bitů -9223372036854775808 +9223372036854775807 a používá se tam, kde typ int není schopen pojmout takovou hodnotu čísla.

		// declaration and assignment of value type long
		long n = 22337203685477580L;
		// print formated value
		System.out.printf("The value of x is %d%n", n); // 22337203685477580
		System.out.format("%+,8d%n%n", n); // +22 337 203 685 477 580

		// declaring more variables in single statement
		long lo1 = 12L, lo2 = 56, lo3 = 1455555555589L;

		// long range of value
		System.out.println(Long.MAX_VALUE); // 9223372036854775807
		System.out.println(Long.MIN_VALUE); // -9223372036854775808

		// check if a string is a valid number in Java example
		// convert string to long Java example
		String sLong = "1288888888888888";
		long longParse = Long.parseLong(sLong);

		// convert strings to numbers
		long longFromString = (Long.valueOf(sLong)).longValue();

		// long to string in Java example code
		Long longObj = new Long(229999999999L);
		String str = longObj.toString();
		// else
		Long longS = 888888888888L;
		String strLong = longS.toString();

		// compare two long variables
		Long longComp1 = 5555L;
		if (longComp1.equals(55555555L))
			System.out.print("true");

		// compares the two specified long values in Java example

		int i = longS.compareTo(444444L); // -1 first < second
		// 0 first == second
		// 1 first > second
		System.out.print(i);
