I wanted to implement a search dialog in my android project. and I don't understand what I'm missing on showing the search dialog to the user.
Here's the manifest for the Activity that suppose to launch the search:
<activity
android:name=".ArrowsActivity"
android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<meta-data android:name="android.app.default_searchable"
android:value=".Searchable" />
</activity>
Here's the manifest for the Searchable Activity:
<activity
android:name=".Searchable"
android:launchMode="singleTop"
android:label="#string/title_activity_searchable" >
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data android:name="android.app.searchable"
android:resource="#xml/searchable"/>
</activity>
Here's the searchable.xml:
<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:hint="#string/search_hint"
android:label="#string/search_label">
</searchable>
Searchable class:
public class Searchable extends ListActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_searchable);
handleIntent(getIntent());
}
#Override
protected void onNewIntent(Intent intent) {
setIntent(intent);
handleIntent(intent);
}
private void handleIntent(Intent intent) {
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
// doMySearch(query);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_searchable, menu);
return true;
}
}
SO.. how do I pop the search box to the user> what am I missing?
Just call onSearchRequested() somewhere, this will start the search activity declared in your manifest.

I have completely followed the Docs on this regard.
I made searchable.xml file
added new activity to handle the query once search is made.
I updated the manifest file accordingly.
My problem is that the new activity is not being called at all as if there is something wrong with the manifest.
Here's the xml file:
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="#string/app_name"
android:hint="#string/search_hint" >
</searchable>
Here's the manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.sultanraja.notes">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".SearchResultsActivity">
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data android:name="android.app.searchable"
android:resource="#xml/searchable" />
</activity>
<activity android:name=".NoteActivity" />
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
And here's the new activity code meanwhile:
public class SearchResultsActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search_results);
handleIntent(getIntent());
}
#Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
handleIntent(intent);
}
private void handleIntent(Intent intent) {
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
Toast.makeText(getApplicationContext(),"your Query is " + query, Toast.LENGTH_SHORT).show();
//use the query to search your data somehow
}
}
}
The Toast is never happening and a breakpoint in the onCreate method is never reached.
what is the problem?
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
if(list.contains(query)){
adapter.getFilter().filter(query);
}else{
Toast.makeText(MainActivity.this, "No Match found",Toast.LENGTH_LONG).show();
}
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
// adapter.getFilter().filter(newText);
return false;
}
});
I found the problem in the manifest file:
I added the following:
<meta-data
android:name="android.app.default_searchable"
android:value=".SearchResultsActivity" />
this part was added to mainActivity and that was not part of the documentation.
thanks.
So I am redoing my app so that there will be an animation on the start screen of the app. The only problem is it seems you cannot start an app with a view class. At least I'm not really sure if you can. Here is my code. With this code i get a launcher activity not found in the console?
public class SplashLaunch extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.splashlaunch);
final Main d = new Main(this);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
setContentView(d);
}
}, 5000);
}
}
Here is the manifest file. I have a feeling that I'm going to need to change this.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.Tripps.thesimplegame"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="12"
android:targetSdkVersion="22" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity

</manifest>
Likely somewhere in your launcher activity you have an onCreate method:
public class YourActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.foobar);
}
}
Just change the setContentView to your custom view:
public class YourActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
MyCustomView view = new MyCustomView(this);
setContentView(view);
}
}
The Activity that you want to start when the app first starts MUST have the following Intent filter:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
Hi everybodi!
I'm new to Android programming and am trying to create a QR code reader app with Zxing. When I start my application in my phone, it gives me this error message. The app is started, after I push the button and then this is thrown... What is the problem?
Here is my code: This is the MainActivity
package com.example;
public class MainActivity extends Activity {
private Button scan;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
scan= (Button)findViewById(R.id.button1);
scan.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
startActivityForResult(intent, 0);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
String contents = intent.getStringExtra("SCAN_RESULT");
String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
// Handle successful scan
} else if (resultCode == RESULT_CANCELED) {
// Handle cancel
Log.i("App","Scan unsuccessful");
}
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
And this is my AndoridManifest

I have created a sample android application for receiving push messages from Parse. I had followed this video tutorial. The application is working fine and I am able to receive push notifications.
The classes required are as follows:
ParseApplication class:
public class ParseApplication extends Application {
#Override
public void onCreate() {
super.onCreate();
// Add your initialization code here
Parse.initialize(this, "ygdC4y3uzCe0TOEPOfB1U469Gg5ZJGxF2OGlNKCG", "Tk5ZlDiWWVJm2Xio5IiXk0KI5JM1jrvGPOSpFxzE");
PushService.setDefaultPushCallback(ParseApplication.this, SampleClass.class);
ParseUser.enableAutomaticUser();
ParseACL defaultACL = new ParseACL();
// If you would like all objects to be private by default, remove this line.
defaultACL.setPublicReadAccess(true);
ParseACL.setDefaultACL(defaultACL, true);
}
}
ParseStarterProjectActivity class:
public class ParseStarterProjectActivity extends Activity {
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ParseAnalytics.trackAppOpened(getIntent());
}
}
SampleClass class:
public class SampleClass extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sample_class);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.sample_class, menu);
return true;
}
}
The manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.parse.starter"
android:versionCode="1"
android:versionName="1.0" >

</intent-filter>
</receiver>
<activity
android:name="com.parse.starter.SampleClass"
android:label="#string/title_activity_sample_class" >
</activity>
</application>
</manifest>
Now I want to get text from the push notifications when the user receives them. What should I do to get the text from the notifications?
This is the url to the push notification server.
I even went though this.
I had to change the SampleClass Activity like this:
public class SampleClass extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sample_class);
Intent intent = getIntent();
Bundle extras = intent.getExtras();
String jsonData = extras.getString( "com.parse.Data" );
Log.i("Data Received:", jsonData);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.sample_class, menu);
return true;
}
The rest is as it is. I referred this link.
I try to share a post on google+ but I obtain this Exception. The Activity that creates the Exception is ExampleActivity and this is its code:
public class ExampleActivity extends Activity implements OnClickListener,
ConnectionCallbacks, OnConnectionFailedListener {
private static final String TAG = "ExampleActivity";
private static final int REQUEST_CODE_RESOLVE_ERR = 9000;
private ProgressDialog mConnectionProgressDialog;
private PlusClient mPlusClient;
private ConnectionResult mConnectionResult;
#Override//onCreate
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_example);
mPlusClient = new PlusClient.Builder(this, this, this)
.setVisibleActivities("http://schemas.google.com/AddActivity","http://schemas.google.com/BuyActivity")
.build();
// Progress bar to be displayed if the connection failure is not resolved.
mConnectionProgressDialog = new ProgressDialog(this);
mConnectionProgressDialog.setMessage("Signing in...");
Button shareButton = (Button) findViewById(R.id.share_button);
shareButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// Launch the Google+ share dialog with attribution to your app.
Intent shareIntent = new PlusShare.Builder()
.setType("text/plain")
.setText("Welcome to
the Google+ platform.")
.setContentUrl(Uri.parse("https://developers.google.com/+/"))
.getIntent();
startActivityForResult(shareIntent, 0);
}
});
}
#Override//onStart
protected void onStart() {
super.onStart();
mPlusClient.connect();
}
#Override//onStop
protected void onStop() {
super.onStop();
mPlusClient.disconnect();
}
#Override// onConnectionFailed
public void onConnectionFailed(ConnectionResult result) {
if (mConnectionProgressDialog.isShowing()) {
// The user clicked the sign-in button already. Start to resolve
// connection errors. Wait until onConnected() to dismiss the
// connection dialog.
if (result.hasResolution()) {
try {
result.startResolutionForResult(this, REQUEST_CODE_RESOLVE_ERR);
} catch (SendIntentException e) {
mPlusClient.connect();
}
}
}
// Save the result and resolve the connection failure upon a user click.
mConnectionResult = result;
}
#Override //onActivityResult
protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
if (requestCode == REQUEST_CODE_RESOLVE_ERR && responseCode == RESULT_OK) {
mConnectionResult = null;
mPlusClient.connect();
}
}
// #Override
// public void onConnected(Bundle connectionHint) {
// String accountName = mPlusClient.getAccountName();
// Toast.makeText(this, accountName + " is connected.", Toast.LENGTH_LONG).show();
// }

Toast.makeText(this, accountName + " is connected.", Toast.LENGTH_LONG).show();
}
#Override//onConnected

Try and clean the project, uninstall your app from device and reinstall.
