IllegalArgumentException Unknown Uri content SearchableDict
If you change the package name, you have to add new package name in:
DictionaryProvider.java
Do not forget change package name in all java class and xml/searchable.xml
In my project I changed like this:
DictionaryProvider.java
public class DictionaryProvider extends ContentProvider {
String TAG = "DictionaryProvider";
// public static String AUTHORITY = "com.example.android.searchabledict.DictionaryProvider";
// change to your new package name
public static String AUTHORITY = "com.myweb.mysubdomen.searchabledict.DictionaryProvider";
public static final Uri CONTENT_URI = Uri.parse("content://" + AUTHORITY + "/dictionary");
// in AndroidManifest.xml
//change com.example.android to your package e.g. com.myweb.mysubdomen
<!-- Provides search suggestions for words and their definitions. -->
<provider android:name="com.example.android.searchabledict.DictionaryProvider"
android:configChanges="keyboard|keyboardHidden|orientation"
android:authorities="com.example.android.searchabledict.DictionaryProvider" />
<!-- Points to searchable activity so the whole app can invoke search. -->
<meta-data android:name="android.app.default_searchable"
android:configChanges="keyboard|keyboardHidden|orientation"
android:value=".SearchableDictionary" />
// I change like this:
<!-- Provides search suggestions for words and their definitions. -->
<provider android:name=".DictionaryProvider"
android:configChanges="keyboard|keyboardHidden|orientation"
android:authorities="cz.okhelp.android.searchabledict.DictionaryProvider" />
<!-- Points to searchable activity so the whole app can invoke search. -->
<meta-data android:name="android.app.default_searchable"
android:configChanges="keyboard|keyboardHidden|orientation"
android:value=".SearchableDictionary" />
Do not forget change package name in all java class and xml/searchable.xml
In my project I changed like this:
<searchable xmlns:android="//schemas.android.com/apk/res/android"
android:label="@string/search_label"
android:hint="@string/search_hint"
android:searchSettingsDescription="@string/settings_description"
android:searchSuggestAuthority="cz.okhelp.android.searchabledict.DictionaryProvider"
android:searchSuggestIntentAction="android.intent.action.VIEW"
android:searchSuggestIntentData="content://cz.okhelp.android.searchabledict.DictionaryProvider/dictionary"
android:searchSuggestSelection=" ?"
android:searchSuggestThreshold="1"
android:includeInGlobalSearch="true"

EditText myEdit = findViewById(R.id.myEdit);
myEdit.setHint(R.string.app_name);

If you create a button or view programmatically with OnClickListener you can set a tag key before button in parent layout is added.
And get correct button by this tag getTag() instead getId() in OnClickListener etc.
And get correct button by this tag getTag() instead getId() in OnClickListener etc.
Button button = new Button(getApplicationContext());
int idOfButton = button.getId(); // return -1
button.setTag("my_button");
String sTag = (String) button.getTag(); // return "my_button"
public class MainActivity extends Activity implements OnClickListener {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
LinearLayout layout = (LinearLayout) findViewById(R.id.layout);
RadioGroup radioGroup = new RadioGroup(this);
LinearLayout.LayoutParams p = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.FILL_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT
);
layout.addView(radioGroup, p);
RadioButton radioButtonView = new RadioButton(this);
radioButtonView.setText("RadioButton");
radioButtonView.setOnClickListener(this);
radioGroup.addView(radioButtonView, p);

}
public void onClick(View view) {
try {
String s = ((RadioButton) view).getText().toString();
Toast.makeText(MainActivity.this, "This is: " + s,
Toast.LENGTH_LONG).show();
}
catch (Exception e1) {
