Android: how to make keyboard enter button say "Search" and handle its click?
I can't figure this out. Some apps have an EditText (textbox) with the help of which, when you touch 开发者_高级运维it and it brings up the on-screen keyboard, the keyboard has a "Search" button instead of an enter key.
I want to implement this. How can I implement that Search button and detect the press of the Search button?
Edit: found how to implement the Search button; in XML, android:imeOptions="actionSearch"
or in Java, EditTextSample.setImeOptions(EditorInfo.IME_ACTION_SEARCH);
. But how do I handle the user pressing that Search button? Does it have something to do with android:imeActionId
?
In the layout set your input method options to search.
<EditText
android:imeOptions="actionSearch"
android:inputType="text" />
In the java add the editor action listener.
editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_SEARCH) {
performSearch();
return true;
}
return false;
}
});
Hide keyboard when user clicks search. Addition to Robby Pond answer
private void performSearch() {
editText.clearFocus();
InputMethodManager in = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
in.hideSoftInputFromWindow(editText.getWindowToken(), 0);
//...perform search
}
In xml
file, put imeOptions="actionSearch"
and inputType="text"
, maxLines="1"
:
<EditText
android:id="@+id/search_box"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/search"
android:imeOptions="actionSearch"
android:inputType="text"
android:maxLines="1" />
In Kotlin
evLoginPassword.setOnEditorActionListener { _, actionId, _ ->
if (actionId == EditorInfo.IME_ACTION_DONE) {
doTheLoginWork()
}
true
}
Partial Xml Code
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginTop="8dp"
android:paddingLeft="24dp"
android:paddingRight="24dp">
<EditText
android:id="@+id/evLoginUserEmail"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/email"
android:inputType="textEmailAddress"
android:textColor="@color/black_54_percent" />
</android.support.design.widget.TextInputLayout>
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginTop="8dp"
android:paddingLeft="24dp"
android:paddingRight="24dp">
<EditText
android:id="@+id/evLoginPassword"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/password"
android:inputType="textPassword"
android:imeOptions="actionDone"
android:textColor="@color/black_54_percent" />
</android.support.design.widget.TextInputLayout>
</LinearLayout>
by XML:
<EditText
android:id="@+id/search_edit"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/search"
android:imeOptions="actionSearch"
android:inputType="text" />
By Java:
editText.clearFocus();
InputMethodManager in = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
in.hideSoftInputFromWindow(searchEditText.getWindowToken(), 0);
This answer is for TextInputEditText :
In the layout XML file set your input method options to your required type. for example done.
<com.google.android.material.textfield.TextInputLayout
android:id="@+id/textInputLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<com.google.android.material.textfield.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:imeOptions="actionGo"/>
</com.google.android.material.textfield.TextInputLayout>
Similarly, you can also set imeOptions to actionSubmit, actionSearch, etc
In the java add the editor action listener.
TextInputLayout textInputLayout = findViewById(R.id.textInputLayout);
textInputLayout.getEditText().setOnEditorActionListener(new
TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_GO) {
performYourAction();
return true;
}
return false;
}
});
If you're using kotlin :
textInputLayout.editText.setOnEditorActionListener { _, actionId, _ ->
if (actionId == EditorInfo.IME_ACTION_GO) {
performYourAction()
}
true
}
