Android ime 选项不起作用

Question

我正在尝试为 android ime 选项设置一个监听器，它将 EditText 的值存储在共享首选项中。我已经这样设置了，但是当我按下键盘上的“return”键时，什么也没有发生，它也永远不会进入监听器。关于我为什么做错的任何想法？

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_settings);

    mDone = (Button) findViewById(R.id.done);
    mTemperature = (EditText) findViewById(R.id.temperature);

    mDone.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {

            int action = event.getAction();
            if (actionId == EditorInfo.IME_ACTION_DONE) {
                // Do whatever you want here
                SharedPreferences preferences = getSharedPreferences(SHARED_PREFERENCES, Context.MODE_PRIVATE);
                SharedPreferences.Editor edit = preferences.edit();

                int updateSweater = Integer.parseInt(mTemperature.getText().toString());
                edit.remove("sweater");
                edit.putInt("sweater", updateSweater);
                edit.commit();
                preferences.getInt("sweater", 0);

                Toast.makeText(SettingsActivity.this, "Sweater Weather Updated", Toast.LENGTH_SHORT).show();

                Intent intent = new Intent(SettingsActivity.this, MainActivity.class);
                startActivity(intent);
                return true;
            }
            return false;
        }
    });
}

这就是我设置 EditText 的方式

<EditText
    android:id="@+id/temperature"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textColor="@color/white"
    android:textColorHint="@color/gray"
    android:textSize="25sp"
    android:layout_centerHorizontal="true"
    android:hint="Farenheit"
    android:inputType="phone"
    android:imeOptions="actionDone"/>

我认为它不起作用，因为 setOnEditorActionListener 应该定义到您的 EditText(而不是您的 Button)。

mTemperature = (EditText) findViewById(R.id.temperature);

mTemperature.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {

        int action = event.getAction();
        if (actionId == EditorInfo.IME_ACTION_DONE) {
            // Do whatever you want here
            SharedPreferences preferences = getSharedPreferences(SHARED_PREFERENCES, Context.MODE_PRIVATE);
            SharedPreferences.Editor edit = preferences.edit();

            int updateSweater = Integer.parseInt(mTemperature.getText().toString());
            edit.remove("sweater");
            edit.putInt("sweater", updateSweater);
            edit.commit();
            preferences.getInt("sweater", 0);

            Toast.makeText(SettingsActivity.this, "Sweater Weather Updated", Toast.LENGTH_SHORT).show();

            Intent intent = new Intent(SettingsActivity.this, MainActivity.class);
            startActivity(intent);
            return true;
        }
        return false;
    }
});

如果在mDone点击后需要做任何 Action ，最好设置一个ClickListener到mDone
