My Android Tip

 - Use at your own risk! lol, ㅋㅋㅋ

내가 작업한 것 중에서 유용한 Tip 들을 정리 해본다.

android:layout_width="fill_parent"
android:layout_height="wrap_contents"
android:clickable="true"
android:paddingLeft="5px"
android:paddingRight="5px"

 - seekbar.xml: Change "(" to "<"
(layer-list xmlns:android="http://schemas.android.com/apk/res/android")
    (item android:id="@android:id/background")
     (clip android:drawable="@drawable/bg" /)

    (item android:id="@android:id/progress")
(clip android:drawable="@drawable/progress" /)
(/item)
(/layer-list)

 - seekbar_thumb.xml: Change "(" to "<"

 (item android:state_focused="true"
android:drawable="@drawable/thumb_button_focused" /)
 (item android:state_focused="false"
android:drawable="@drawable/thumb_button_normal" /)
(/selector)

 - Thread:

Thread.sleep( 1000 );

if( m_MediaPlayer.isPlaying() == false )

break;

m_Handler.sendMessage( m_Handler.obtainMessage() );

 - SeekBar:

        // SeekBar

        m_SeekBar = (SeekBar)findViewById( R.id.SeekBar01 );

        m_SeekBar.setProgress( 0 );

        m_SeekBar.setClickable( true );

 - Handler:

m_Handler = new Handler() {

public void handleMessage(android.os.Message msg) {

if( (m_MediaPlayer == null) ) {

m_SeekBar.setProgress( 0 );

// something

// ...

return;

}

if( m_MediaPlayer.isPlaying() ) {

int position = m_MediaPlayer.getCurrentPosition();

int duration = m_MediaPlayer.getDuration();

if( m_SeekBar != null ) {

if( duration > 0 ) {

long pos = m_MediaPlayer.getDuration() * position / duration;

m_SeekBar.setProgress( m_MediaPlayer.getCurrentPosition() );

}

// something

// ...

// NOTE: below code are just sample...

// ...

int m = (int) Math.floor(m_MediaPlayer.getCurrentPosition()/(1000*60));

int s = (int) Math.floor((m_MediaPlayer.getCurrentPosition()-(1000*60)*m)/1000);

m_CurrentSec = (m * 60) + s;

String strM = m < 10 ? "0" + Integer.toString( m ) : Integer.toString( m );

String strS = s < 10 ? "0" + Integer.toString( s ) : Integer.toString( s );

m_strCurrentMS = strM + ":" + strS;

Log.d( "THREAD", "Cur = " + m_CurrentSec + ", Duration = " + m_DurationSec );

if( ((m_CurrentSec+1) >= m_DurationSec) || ((m_CurrentSec+1) >= m_DurationSec) ) {

Log.d( "THREAD", "THREAD END..." );

m_strCurrentMS = "00:00";

if( m_MediaPlayer != null ) {

m_MediaPlayer.release();

m_MediaPlayer = null;

}

m_SeekBar.setProgress( 0 ); // reset

// something

// ...

}

}

}

else {

Log.d( "THREAD", "Playing == false" );

m_strCurrentMS = "00:00";

if( m_MediaPlayer != null ) {

m_MediaPlayer.release();

m_MediaPlayer = null;

}

m_SeekBar.setProgress( 0 ); // reset

// something

// ...

}

};

};

 - SeekBarListener:
NOTE: http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob_plain;f=core/java/android/widget/MediaController.java;hb=71beeab14a891297b6658c4aeb47557083091aa1

m_SeekBar.setOnSeekBarChangeListener( new OnSeekBarChangeListener() {

public void onStopTrackingTouch(SeekBar seekBar) {

// TODO Auto-generated method stub

   if( m_MediaPlayer != null )

m_CurrentPosition = m_MediaPlayer.getCurrentPosition();
   else
       m_SeekBar.setProgress( 0 );

}

public void onStartTrackingTouch(SeekBar seekBar) {

// TODO Auto-generated method stub

}

public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {

// TODO Auto-generated method stub

if( !fromUser )

return;

   if( m_MediaPlayer != null ) {

long duration = m_MediaPlayer.getDuration();

//long newposition = (duration * progress) / 1000L;

long newposition = (duration * progress) / m_MediaPlayer.getDuration();

m_MediaPlayer.seekTo( (int) newposition);
   }

}

}

);

// ---------------------------------------------

:: Disable SeekBar Touch Event

seekBar.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
//return false;
return true;
}
});
