Right I've looked at a shed load of tutorials, questions and so on but none have worked, so I don't need more links, I just need a fix for my current code..
So far I have this:
public class FullscreenActivity extends Activity {
protected int[] mThumbIds;
#SuppressWarnings("unused")
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fullscreen);
// get intent data
Intent i = getIntent();
// Selected image id
final int position = i.getExtras().getInt("id");
ImageAdapter imageAdapter = new ImageAdapter(this);
ImageView imageView = (ImageView) findViewById(R.id.full_image_view);
Button SetWallpaper = (Button)findViewById(R.id.setwallpaper);
imageView.setImageResource(imageAdapter.mThumbIds[position]);
}
private Object[] imageIDs;
private int position;
public void onClick(View arg0) {
try {
WallpaperManager.getInstance(this).setResource((Integer) imageIDs[position]);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
But when I click the button once the picture has been selected, it doesn't do anything?
I also have the permission in the manifest but it still doesn't work, so any help would be hugely appreciated
Thank you
I'm not sure if this has anything to do with it or not but I'm testing the app on a Samsung Galaxy S4
May be it can relate..

You're missing some braces and semicolons, and you've got an #Oveerride in there as well.
Try this, it should compile:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Gallery gallery = (Gallery) findViewById(R.id.gallery1);
//create adapter Gallery
gallery.setAdapter(new ImageAdapter(this));
imageView = (ImageView) findViewById(R.id.imageView1);
gallery.setOnItemClickListener( new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int arg2, long arg3) {
Toast.makeText(getApplicationContext(), "pic:" + arg2, Toast.LENGTH_SHORT).show();
imageView.setImageResource(pics[arg2]);
}
});
// look for the button we set in the view
ImageButton cameraButton = (ImageButton)
findViewById(R.id.button_camera);
// set a listener on the button
cameraButton.setOnClickListener(cameraListener);

in this above code find this code: here i want to perform save image from viewpager to sd card
// Save ViewPager current image to sd card on button click
Button b1 = (Button) findViewById(R.id.wll);
b1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v2) {
// // TODO Auto-generated method stub
// Save ViewPager current image to sd card
}
});
Try something like this:
String filename;
Bitmap imageBitmap;
//....
//set file name and bitmap
//....
File imageFile = new File(Environment.getExternalStorageDirectory(), filename);
FileOutputStream out;
try {
out = new FileOutputStream(imageFile);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
outStream.flush();
outStream.close();
success = true;
} catch (Exception e) {
Log.e(TAG, "Error writing to file: ", e);
} finally {
if (out != null) {
try {
out.close();
} catch (IOException e) {

When switching intents I lose data from the previous onActivityResult I need it to keep both numbers it gets from the user, currently it will keep one number, then when the next is entered it loses the previous, here's code:
package com.eric.theworks;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends Activity implements OnClickListener {
Button width, height, calc;
TextView area;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
width = (Button) findViewById(R.id.button1);
height = (Button) findViewById(R.id.button2);
calc = (Button) findViewById(R.id.button3);
area = (TextView) findViewById(R.id.textView1);
width.setOnClickListener(this);
height.setOnClickListener(this);
calc.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(this, Numbers.class);
switch (v.getId()) {
case R.id.button1:
// width
i.putExtra("numbers", "width");
startActivityForResult(i, 1);
break;
case R.id.button2:
// height
i.putExtra("numbers", "height");
startActivityForResult(i, 1);
break;
case R.id.button3:
// calc
break;
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (data.getExtras().containsKey("widthInfo")){
width.setText(data.getStringExtra("widthInfo"));
}
if (data.getExtras().containsKey("heightInfo")){
height.setText(data.getStringExtra("heightInfo"));
}
}
}
package com.eric.theworks;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class Numbers extends Activity implements OnClickListener {
EditText number;
Button sendInfo;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.numbers);
number = (EditText) findViewById(R.id.editText1);
sendInfo = (Button) findViewById(R.id.button1);
sendInfo.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
String s = number.getText().toString();
Intent i = getIntent();
String msg = i.getStringExtra("numbers");
if (msg.contentEquals("width")) {
i.putExtra("widthInfo", s);
setResult(RESULT_OK, i);
finish();
}
if (msg.contentEquals("height")) {
i.putExtra("heightInfo", s);
setResult(RESULT_OK, i);
finish();
}
}
}
You can use static variable to store the previous data.
Declare static string globally.
static String widthInfo="";
static String heightInfo="";
Also Give different Requestcode.
case R.id.button1:
// width
i.putExtra("numbers", "width");
startActivityForResult(i, 1);
break;
case R.id.button2:
// height
i.putExtra("numbers", "height");
startActivityForResult(i, 2);
Then use it in your onActivityResult.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case (1): {
if (data.getExtras().containsKey("widthInfo")){
widthInfo=data.getStringExtra("widthInfo")
width.setText(data.getStringExtra("widthInfo"));
} else {
height.setText(heightInfo);
width.setText(widthInfo);
}
}
break;
case (2):
{
if (data.getExtras().containsKey("heightInfo")){
heightInfo=data.getStringExtra("heightInfo")
height.setText(data.getStringExtra("heightInfo"));
}else {
height.setText(heightInfo);
width.setText(widthInfo);
}
}
break;
}
}
you can use Bundle to pass data from one activity to another rather than the intent directly. for example:
Bundle b = new Bundle();
b.putString("SingleClick",a );
b.putString("LongClick", "no");
i.putExtras(b);
and to get the data in another activity use
Bundle bundle = getIntent().getExtras();
String admin = bundle.getString("LongClick");
String s = number.getText().toString();
Intent i = getIntent();
String msg = i.getStringExtra("numbers");
if (msg.contentEquals("width")) {
i.putExtra("widthInfo", s);
setResult(RESULT_OK, i);
finish();
}
make sure the string s has any values....
I'm trying to use a barcode scanner and then take that input and use in another activity to open with a url. I've been able to get the data to return, just not in another activity and haven't seen any projects exactly like this. I'm not sure if it has to do with intent or how I'm calling the string. The webview in the second java works but doesn't take the string. Thanks for the help!
Scanner.java (which works okay)
package com.pangolin.rollin.ts;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;
public class Scanner extends Activity {
TextView tvStatus;
TextView tvResult;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_scanner);
Button websku = (Button) findViewById(R.id.btnsku);
websku.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent myintent = new Intent(Scanner.this, Websku.class);
startActivity(myintent);
}
});
tvStatus = (TextView) findViewById(R.id.tvStatus);
tvResult = (TextView) findViewById(R.id.tvResult);
Button scanBtn = (Button) findViewById(R.id.btnScan);
// in some trigger function e.g. button press within your code you
// should add:
scanBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
try {
Intent intent = new Intent(
"com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "QR_CODE_MODE,PRODUCT_MODE");
startActivityForResult(intent, 0);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
Toast.makeText(getApplicationContext(), "ERROR:" + e, Toast.LENGTH_LONG)
.show();
}
}
});
}
// In the same activity you’ll need the following to retrieve the results:
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
tvStatus.setText(intent.getStringExtra("SCAN_RESULT_FORMAT"));
tvResult.setText(intent.getStringExtra("SCAN_RESULT"));
} else if (resultCode == RESULT_CANCELED) {
tvStatus.setText("Press a button to start a scan.");
tvResult.setText("Scan cancelled.");
}
}
}
}
And websku.java (doesn't work, supposed to take results from previous activity.
package com.pangolin.rollin.ts;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class Websku extends Activity {
final Activity activity = this;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = getIntent();
String sku = intent.getStringExtra("SCAN_RESULT");
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.activity_websku);
WebView webView = (WebView) findViewById(R.id.webview_sku);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
activity.setTitle("Loading...");
activity.setProgress(progress * 100);
if (progress == 100)
activity.setTitle(R.string.title_activity_websku);
}
});
webView.setWebViewClient(new WebViewClient() {
#Override
public void onReceivedError(WebView view, int errorCode,
String description, String failingUrl) {
// Handle the error
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
webView.loadUrl("http://m.radioshack.com/radioshack/catalog/searchList.do?categoryId=&keyword="+sku);
};
}
You don't set any extra to Websku intent:
websku.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent myintent = new Intent(Scanner.this, Websku.class);
startActivity(myintent);
}
});
Should be:
websku.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent myintent = new Intent(Scanner.this, Websku.class);
myintent.putExtra("somename", somevalue);
startActivity(myintent);
}
});
You don't set the extras for the websku Activity. Save the intent returned from the scanner:
private Intent mWebskuIntent;
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
mWebskuIntent = intent;
// more of your code
Then when you start the websku Activity make a copy of the saved intent which will copy also the extras returned from the scanner:
Intent myintent = new Intent(mWebskuIntent);
myintent.setClass(Scanner.this, Websku.class);
startActivity(myintent);
You might want to check for mWebskuIntent being null as well.
i have 2 activity. activity saveData and activity androidCamera
first, i have a form in saveData. when form is already inputed except EditText "Upload Photo". then, i click button camera to take a uri/path image. when finish() the camera activity send value uri/path back to SaveData form Activity. the question is how to updating EditText "Upload Photo" in SaveData so when i take picture, the camera send path/uri inside EditText "Upload Photo"?
this is my Activity AndroidCamera

Write below line before setContentView(R.layout.save); in onCreate() method of SaveData Activity, it will solve your problem.
EditText edt = (EditText) findViewById(R.id.txtStatus);
You should call the method "setResult" to submit your result to the calling Activity and then check the result in "onResume".
But a general hint for you. In Android you can leverage the Intent system for the benefit of the user. One example would be to let the user choose his camera app to take the picture instead of writing your own activity for this. This saves you a lot of time and the user is happy he can use the specific camera app which suits his needs and that he hunted down for hours and paid for it.
This is you have done in AndroidCamera activity :
Bundle bundle = new Bundle();
bundle.putString("path", uriTarget.toString());
Intent newIntent = new Intent(AndroidCamera.this, SaveData.class);
newIntent.putExtras(bundle);
startActivityForResult(newIntent, 0);
Change this line
startActivityForResult(newIntent, 0);
to
startActivity(newIntent);
Now, Just call this code to your SaveData Activity :
UPDATE :
String imagePath="";
if(getIntent().getExtras() != null){
imagePath = getIntent().getExtras().getString("path");
your_editText.setText(imagePath);
}
Hope this helps you.
Thanks.
