Button02 = (Button) findViewById(R.id.Button02);
final SeekBar seekBar01 = (SeekBar) findViewById(R.id.SeekBar01);
final Random anyrandom = new Random();
final EditText EditText01 = (EditText) findViewById(R.id.EditText01);
Button01.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// i need help to move to other activity in my app with this
// intent
Intent asdintenet = new Intent(this, secjavafile);
startActivity(asdintenet);
// this is the random i want to use (asdrandom)outside this
// method
int asdrandom = anyrandom.nextInt(30) + 1;
seekBar01.setProgress(asdrandom);
}
});
Button02.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
});
seekBar01
.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
@Override
public void onProgressChanged(SeekBar seekBar,
int progress, boolean fromUser) {
/*
* I WANT to use the random here e.g
* EditText01.setText("progress is"+asdrandom);when i
* use progress int the app crash
*/
}
@Override

as u c I'm beginner

i;ve solved one

[Q][DEV]Android Development Maps Question

I'm trying to develop (for the liveview) using an SDK and need to get a bitmap of Google Maps.
Code:
//Map Section
public class myMap extends MapActivity {
MapView mapView;
Bitmap bitmap;
boolean created = false;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
createMap();
}
public void createMap()
{
// build map and mark point
mapView = new MapView(this, "keykeykeykeykeykey");
mapView.setBuiltInZoomControls(false);
GeoPoint point = new GeoPoint(52242730,-884211);
mapView.getController().animateTo(point);
mapView.preLoad();
// copy MapView to canvas
bitmap = Bitmap.createBitmap(400, 800, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
mapView.draw(canvas);
PluginUtils.sendTextBitmap(mLiveViewAdapter, mPluginId, "Loading Map...", 128, 12);
created = true;
}
public void displayMap()
{
if (created == false)
{
createMap();
}
//Display map on device
Bitmap mybit = Bitmap.createBitmap(128, 128, Bitmap.Config.ARGB_8888);
for(int i = 0; i < 128; i++)
{
for(int j = 0; j < 128; j++)
{
mybit.setPixel(i, j, bitmap.getPixel(i, j));
}
}
//white pixel for debugging
mybit.setPixel(64, 64, Color.WHITE);
}
@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
Is what I've got so far, the code in createMap() was in onCreate() but It didn't seem to be called.
Now it just force closes.
Anyone know how to help? Is there a better place to ask development questions?
Thanks.
-=Edit=-
Oh, and here's the routine calling the map thing, every couple of seconds.
Code:
private class Timer implements Runnable {
@Override
public void run() {
// TODO Auto-generated method stub
myMap theMap = new myMap();
theMap.displayMap();
}
}

Okay, looks like you cant use google street map like this.
Anyone looking for similar solution, I used open street map and downloaded 'slipery tiles' png's. They provide java routines for finding the tile url from lat/lon.

Long Press on Home

Hello, I have never done this for Android, though I do develop web apps. I'd like to give it a shot with the Android OS and my first project would be to modify behavior of long pressing a Home Button on our Note II's. I found some information on the web by using a function to hook into the KeyLongPress and Key ID.
What I would like to know, if where do I begin to start adding my custom functions? Do I create a separate file or put the function in an existing file?
How do I make this apply only during the lockscreen or home screen?
Using the example below, I imagine I need to create a folder called com.example.demo, but not sure where and what else would be needed.
Code:
package com.example.demo;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.KeyEvent;
import android.view.Menu;
public class TestVolumeActivity extends Activity {
boolean flag = false;
boolean flag2 = false;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash_screen);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_splash_screen, menu);
return true;
}
@Override
public boolean onKeyLongPress(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN) {
Log.d("Test", "Long press!");
flag = false;
flag2 = true;
return true;
}
return super.onKeyLongPress(keyCode, event);
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN) {
event.startTracking();
if (flag2 == true) {
flag = false;
} else {
flag = true;
flag2 = false;
}
return true;
}
return super.onKeyDown(keyCode, event);
}
@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN) {
event.startTracking();
if (flag) {
Log.d("Test", "Short");
}
flag = true;
flag2 = false;
return true;
}
return super.onKeyUp(keyCode, event);
}
}
Any help is appreciated.

It would be helpful to take a look at CM code and how the long press hardware key actions, as well as lock screen button actions are implemented.

Not sure if I understood you correctly, but you can't just put the code in a text file like a PHP script and expect it to work You need to compile it first using the Android SDK.
In any case, you can't hook keys globally the way you are suggesting. You'd need to modify the system's framework files (inside android.policy.jar) for it to work, which frankly sounds to be beyond your capabilities at the moment.

Are you talking about in your own app or for your ROM?

[Q] how call activity.java in other one using button listener

I have two class activity that runs perfectly separately (ArduinoBlinkLEDActivity.java and ObjTrackActivity.java) .. I want to merge the two classes in one slass; i want to call the second class in the first one using the onclick activity buttonListener. i think that need to change layouts
please i need your help
ArduinoBlinkLEDActivity.java:
public class ArduinoBlinkLEDActivity extends Activity {
// TAG is used to debug in Android logcat console
private static final String TAG = "ArduinoAccessory";
@override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
while (connected) {
startService(new Intent(this, ArduinoBlinkLEDActivity.class));
}
iptext = (EditText) findViewById(R.id.ipserveur);
connexion = (Button) findViewById(R.id.button2);
deconnexion = (Button) findViewById(R.id.button1);
}
ObjTrackActivity.java :
public class ObjTrackActivity extends Activity {
private static final String TAG = "ObjTrackActivity";
public ObjTrackActivity() {
Log.i(TAG, "Instantiated new " + this.getClass());
}
/** Called when the activity is first created. */
@override
public void onCreate(Bundle savedInstanceState) {
Log.i(TAG, "onCreate");
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(new ObjTrackView(this));
}
ObjTrackView.java:
class ObjTrackView extends SampleViewBase {
private int mFrameSize;
private Bitmap mBitmap;
private int[] mRGBA;
public ObjTrackView(Context context) {
super(context);
}
my test that doesn't work: ArduinoBlinkLEDActivity.java:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
iptext = (EditText) findViewById(R.id.ipserveur);
connexion = (Button) findViewById(R.id.button2);
deconnexion = (Button) findViewById(R.id.button1);
Button btnNextScreen = (Button) findViewById(R.id.btnNextScreen);
//Listening to button event
btnNextScreen.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
//Starting a new Intent
Log.i(TAG, "onCreate");
//super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(new ObjTrackView(this));
}
});

Hi, thank you for using XDA assist.
There is a general forum for android here http://forum.xda-developers.com/android/help where you can get better help and support if you try to ask over there.
Good luck.
