developer.android.com上的editText.setOnEditorActionListener错误

Question

I see this code on developer.android.com for handle the IME_ACTION of the softkeyboard:

EditText editText = (EditText) findViewById(R.id.search);
editText.setOnEditorActionListener(new OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        boolean handled = false;
        if (actionId == EditorInfo.IME_ACTION_SEND) {
            sendMessage();
            handled = true;
        }
        return handled;
    }
});

If you see, this code not working because the mehod OnEditorActionListener is for a TextView type...

So, what are the right method to haddling the IME_ACTION of the softkeyboard?

Answer 1

Please use ButterKnife instead

@OnEditorAction(R.id.editText)
protected boolean actionDo(int actionId){
    if (actionId == EditorInfo.IME_ACTION_DONE) {
        doCalculate();
        return true;
    }
    return false;
}

It works!

You need to specify imeOption prior to responding action

<EditText
    android:id="@+id/search"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:hint="@string/search_hint"
    android:inputType="text"
    android:imeOptions="actionSend" />

And then you can respond to it by using following code:

EditText editText = (EditText) findViewById(R.id.search);
editText.setOnEditorActionListener(new OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        boolean handled = false;
        if (actionId == EditorInfo.IME_ACTION_SEND) {
            sendMessage();
            handled = true;
        }
        return handled;
    }
});

您应该向onEditorAction方法返回false。
