Help School Timetable

[Artjom]

Hello! I am beginner ina android programming, although I started making new app for school. All is good, but there is one problem. How to make when I zoom I can move picture from right to left and from up to down and see all picture. Run my code and you will understand, what I mean.



public class MainActivity extends Activity{

Spinner spin;
TextView tw;
String[] states;
ImageView image;
TypedArray imgs;
ZoomControls zoom;
RelativeLayout rl;

@override
protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

zoom = (ZoomControls) findViewById(R.id.zoomControls);
states = getResources().getStringArray(R.array.klassid);
imgs = getResources().obtainTypedArray(R.array.pildid);
image = (ImageView) findViewById(R.id.imageView);
spin = (Spinner) findViewById(R.id.spinner);
Button b= (Button)findViewById(R.id.button);
rl = (RelativeLayout)findViewById(R.id.RelativeLayout);
image.getLayoutParams().width = 660;
image.getLayoutParams().height = 450;


b.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("https://johvi.ope.ee/auth/"));
startActivity(i);


}
});

//zoomControls
zoom.setOnZoomInClickListener(new View.OnClickListener() {

@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
@override
public void onClick(View v) {
// TODO Auto-generated method stub

float x = image.getScaleX();
float y = image.getScaleY();

image.setScaleX(x + 1);
image.setScaleY(y + 1);
tw.setText("lol");

}
});

zoom.setOnZoomOutClickListener(new View.OnClickListener() {

@override
public void onClick(View v) {
// TODO Auto-generated method stub


float x = image.getScaleX();
float y = image.getScaleY();

image.setScaleX(x - 1);
image.setScaleY(y - 1);

}
});

ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, states);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spin.setAdapter(dataAdapter);

spin.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

@override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
image.setImageResource(imgs.getResourceId(
spin.getSelectedItemPosition(), -1));
}

@override
public void onNothingSelected(AdapterView<?> arg0) {

}
});
}

public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}


public class function implements AdapterView.OnItemSelectedListener {

@override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String str = parent.getItemAtPosition(position).toString();

}

@override
public void onNothingSelected(AdapterView<?> parent) {
tw.setText("Valige klass");
}
}

}
