The sound I am using is from a keyboard being keyboard and was taken from this video = > link
Duration = > 2.577 seconds
I added it to the RAW folder of the project in question and would like to know how to make it play and repeat as long as the animated TextView was not fully played.
TypeWriter:
package genesysgeneration.animatedtext;
import android.content.Context;
import android.os.Handler;
import android.util.AttributeSet;
import android.widget.TextView;
public class TypeWriter extends TextView {
private CharSequence mText;
private int mIndex;
private long mDelay = 1;
public TypeWriter(Context context){
super(context);
}
public TypeWriter(Context context, AttributeSet attrs){
super(context, attrs);
}
private Handler mHandler = new Handler();
private Runnable characterAdder = new Runnable() {
@Override
public void run() {
setText(mText.subSequence(0, mIndex++));
if (mIndex<=mText.length()){
mHandler.postDelayed(characterAdder, mDelay);
}
}
};
public void animatedText(CharSequence text){
mText=text;
mIndex=0;
setText("");
mHandler.removeCallbacks(characterAdder);
mHandler.postDelayed(characterAdder, mDelay);
}
public void setCharacterDelay(long millis){
mDelay=millis;
}
}MainActivity:
package genesysgeneration.animatedtext;
import android.media.MediaPlayer;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MediaPlayer teclado_02 = MediaPlayer.create(MainActivity.this, R.raw.teclado_02);
TypeWriter tv = (TypeWriter)findViewById(R.id.tv);
tv.setCharacterDelay(1);
tv.animatedText("(nova execução) Pirulito ki bate bate, pirulito ki jah bateu!!!\n(nova execução) Pirulito ki bate bate, pirulito ki jah bateu!!!\n(nova execução) Pirulito ki bate bate, pirulito ki jah bateu!!!\n(nova execução) Pirulito ki bate bate, pirulito ki jah bateu!!!\n(nova execução) Pirulito ki bate bate, pirulito ki jah bateu!!!\n(nova execução) Pirulito ki bate bate, pirulito ki jah bateu!!!\n(nova execução) Pirulito ki bate bate, pirulito ki jah bateu!!!\n");
}
