Question

我想在下拉菜单列表中更改语言基础。但此代码无法正常工作。它显示了此问题Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@41141af0.

我无法弄清楚问题在哪里。请任何人帮助我。

public class LanguageChangedActivity extends Activity {
/** Called when the activity is first created. */

private static String[] rangeArray = new String[] { "English", "Franch",
        "Japanies" };
private Spinner rangeSpinner;
String tempRange = "";
String languageToLoad = "";
boolean isFirstTime = true;
int posit=0;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // rangeArray = getResources().getStringArray(R.array.rangeArray);

    languageToLoad = "en"; // your language
    // Locale locale = new Locale(languageToLoad);
    // Locale.setDefault(locale);
    // Configuration config = new Configuration();
    // config.locale = locale;
    // getBaseContext().getResources().updateConfiguration(config,
    // getBaseContext().getResources().getDisplayMetrics());
    this.setContentView(R.layout.main);


    Log.w("isFirstTime onCreate","????");

    // Resources res = getBaseContext().getResources();
    // // Change locale settings in the app.
    // DisplayMetrics dm = res.getDisplayMetrics();
    // android.content.res.Configuration conf = res.getConfiguration();
    // conf.locale = new Locale(languageToLoad.toLowerCase());
    // res.updateConfiguration(conf, dm);

    // range spinner
    rangeSpinner = (Spinner) findViewById(R.id.spinnerLanguage);
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_spinner_item, getResources()
                    .getStringArray(R.array.rangeArray));
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    rangeSpinner.setAdapter(adapter);
    rangeSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {

        public void onItemSelected(AdapterView<?> adapterView, View view,
                int position, long id) {

            posit=position;

            Log.w("isFirstTime onCreate onItemSelected","????");

            if (isFirstTime) {
                isFirstTime = false;
            } else {

                if (position == 0) {

                onConfigurationChanged(config);

            }
        }

        public void onNothingSelected(AdapterView<?> adapterView) {
        }
    });

}

@Override

    rangeSpinner.setAdapter(adapter);


    Log.w("isFirstTime onConfigurationChanged","????");

@Override

}
}

Answer 1

只是为了尝试......
而不是调用onConfigChange()方法...让一个用户定义函数说toChangeConfig(Config c)并在你写的那个函数中执行相同的代码步骤在onConfigChange()中，现在在onItemSelected中调用此函数。

Answer 2

为布局中的根元素指定ID。现在尝试在第二次膨胀内容之前删除AllViews。

这只是猜测，但值得一试。

Answer 3

尝试使用updateConfiguration方法

DisplayMetrics dm = getResources().getDisplayMetrics();
updateConfiguration(config, dm);

Answer 4

外化字符串，使用命名方法让android为你处理它。

你还需要做MKJParekh所说的 - onConfigChange（）是一个回调，而不是你所说的。切换配置时会调用它，所以再放一个

Log.d("MY APP", "::onConfigurationChange() fired!");

等待它出现。此外，该代码不应该在onCreate（）中，而应该在onResume中 - 请记住onCreate（）需要是一个轻量级方法。
