Question

I have implemented multiple seek bar in android like

@Override
public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    sb1=(SeekBar) findViewById(R.id.seekBar1);
    sb2=(SeekBar) findViewById(R.id.seekBar2);
    sb3=(SeekBar) findViewById(R.id.seekBar3);

    tv1=(TextView) findViewById(R.id.textView1);
    tv2=(TextView) findViewById(R.id.textView2);
    tv3=(TextView) findViewById(R.id.textView3);

    sb1.setOnSeekBarChangeListener(this);
    sb2.setOnSeekBarChangeListener(this);
    sb3.setOnSeekBarChangeListener(this);

}

@Override
public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) 
{

    switch (arg0.getId()) 
    {
    case R.id.seekBar1:
        tv1.setText(arg1);
        break;
    case R.id.seekBar2:
        tv2.setText(arg1);
        break;
    case R.id.seekBar3:
        tv3.setText(arg1);
        break;
    }
}

@Override
public void onStartTrackingTouch(SeekBar arg0) 
{
    // TODO Auto-generated method stub

}

@Override
public void onStopTrackingTouch(SeekBar arg0) 
{
    // TODO Auto-generated method stub

}

Whenever I run this app, it gives the following errors:

I don’t know why this is happening. Please help me. Thanxs in advance

Answer 1

You are passing an int into the setText() method of your TextView which is the overload to look for a resource with that ID. You need to change it (and the similar lines) to:

tv1.setText(arg1.toString());
