Open new activity for searchview when search is clicked

Question

I want to open a new activity whenever the search icon is clicked on the mainactivity. This new activity called SearchableActivity will handle all the relevant search results in the listview. I have followed the steps described in this post.

This is what I currently have:

I want to open up the SearchableActivity when the user enters into SearchView.

Here is what my code looks like:

AndroidManifest.xml

     <activity
            android:name=".MainActivity"
            android:launchMode="singleTop">
            <!-- meta tag points to the activity which displays the results -->
            <meta-data
                android:name="android.app.default_searchable"
                android:value=".SearchableActivity" />
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".SearchableActivity"
            android:parentActivityName=".MainActivity">
            <!-- Parent activity meta-data to support 4.0 and lower -->
            <meta-data
                android:name="android.support.PARENT_ACTIVITY"
                android:value=".MainActivity" />
            <!-- meta tag and intent filter go into results activity -->
            <meta-data android:name="android.app.searchable"
                android:resource="@xml/searchable" />
            <intent-filter>
                <action android:name="android.intent.action.SEARCH" />
            </intent-filter>
        </activity>

MainActivity

override fun onCreateOptionsMenu(menu: Menu?): Boolean {
        menuInflater.inflate(R.menu.options_menu, menu)
        val manager = getSystemService(SEARCH_SERVICE) as SearchManager
        (menu?.findItem(R.id.search)?.actionView as SearchView).apply {
            setSearchableInfo(manager.getSearchableInfo(ComponentName(this.context, SearchableActivity::class.java)))

        }
        return true
    }

SearchableActivity

class SearchableActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_searchable)
        Toast.makeText(this@SearchableActivity, "SA created", Toast.LENGTH_LONG).show()
        handleIntent(intent)
    }

    override fun onNewIntent(intent: Intent?) {
        super.onNewIntent(intent)
        if (intent !== null)
            handleIntent(intent)
    }

    private fun handleIntent(intent: Intent) {
        if (Intent.ACTION_SEARCH == intent.action) {
            val query = intent.getStringExtra(SearchManager.QUERY)
            Toast.makeText(this@SearchableActivity, "QUERY: $query", Toast.LENGTH_LONG).show()
        }
    }
}

there is a method that handles option menu item click it is called

override fun onOptionsItemSelected(item: MenuItem): Boolean {
    if(item.itemId == R.id.myItemId){
        startActivity(Intent(applicationContext, searchAcctivity::class.java))
    }
    return super.onOptionsItemSelected(item)
}

this code is written in kotlin, it shouldn't be that different in java just press ctrl + o and it should open a list of override methods search for "onOptionsItemSelected"

I'm not sure what you're trying to do but you can simply pass in the Search query to the intent of the activity at its creation.

First, add a companion object to your SearchableActivity :

  companion object {
        private const val EXTRA_QUERY = "SEARCH_QUERY"

        fun newIntent(context: Context?, query: String): Intent {
            return Intent(context, SearchableActivity::class.java)
                .putExtra(EXTRA_QUERY, query)
        }
    }

My understanding is that you want to open a new activity with the search query from MainActivity, next thing is handling the intent:

         private fun handleIntent(intent: Intent) {
                if (Intent.ACTION_SEARCH == intent.action) {
                    val query = intent.getStringExtra(EXTRA_QUERY)
                    Toast.makeText(this@SearchableActivity, "QUERY: $query", Toast.LENGTH_LONG).show()

            SearchableActivity.newIntent(this, query)            
    }
  }

..et voila.

Open new activity for searchview when search is clicked
