TextSwitcher is useful to animate a label on screen. TextSwitcher animates the current text out and animates the new text. In below example Frist I have created a main layout, In main layout I have added TextSwitcher attributes. See the below example code it will clearly described you how to create TextSwitcher.
Step(1)-MainActivity-
public class MainActivity extends AppCompatActivity {
Button buttonNext;
TextSwitcher textSwitcher;
Animation slide_in_left,slide_out_right;
String[]TextToSwitched={"one","two","three","four","five"};
int curIndex;
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buttonNext =(Button)findViewById(R.id.next);
textSwitcher=(TextSwitcher)findViewById(R.id.textswithcer);
slide_in_left= AnimationUtils.loadAnimation(this,android.R.anim.slide_in_left);
slide_out_right=AnimationUtils.loadAnimation(this,android.R.anim.slide_out_right);
textSwitcher.setInAnimation(slide_in_left);
textSwitcher.setOutAnimation(slide_out_right);
textSwitcher.setFactory(new ViewSwitcher.ViewFactory() {
@Override
public View makeView() {
TextView textView = new TextView(MainActivity.this);
textView.setTextSize(30);
textView.setTextColor(Color.RED);
textView.setGravity(Gravity.CENTER_HORIZONTAL);
textView.setTypeface(Typeface.DEFAULT_BOLD);
textView.setShadowLayer(10, 10, 10, Color.BLUE);
return textView;
}
});
curIndex=0;
textSwitcher.setText(TextToSwitched[curIndex]);
buttonNext.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
if (curIndex == TextToSwitched.length-1){
curIndex=0;
textSwitcher.setText(TextToSwitched[curIndex]);
}else {
textSwitcher.setText(TextToSwitched[++curIndex]);
}
}
});
}
}
Step(2)-main.xml-
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:autoLink="web"
android:text="Microsoft"
android:textStyle="bold"
android:background="#abf299"
android:textSize="25dp" />
<TextSwitcher
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/textswithcer"/>
<Button
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/next"/>
</LinearLayout>
