小编tah*_*pam的帖子

对不起,我的英语不好.

我有一个TextView,它有一个背景图像资源.但是当我点击这个TextView时,Android需要将当前背景图像资源与可绘制文件夹中的R.drawable.bg_images之一进行比较.

bg_image_1 bg_image_2

如果TextView setBackgroundImageResource是bg_image_1并且我单击它,则将TextView背景图像切换为gb_image_2资源.

怎么样？

谢谢

我的目标是在创建上下文之前重写应用程序语言,并且我将使用该上下文来调用其他活动.它可以通过在"onCreate"上对"重新创建()"方法进行校对,但我不想重新创建活动以实现该目标.例如

@Override
protected void attachBaseContext(Context newBase) {

    //null exception here
    SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);

    String langKey = getString(R.string.pref_language_key);
    String langValue = sharedPreferences.getString(langKey, null);

    super.attachBaseContext(ConfigurationUtil.wrapLanguage(newBase, langValue));
}

如果这不可能,那么如何设置用户从设置中选择的应用程序语言？

我在 android studio 的项目文件中得到了红色的 .gradle 粘贴。

我知道有一个类似的问题，但我不明白如何解决它。红色的.gradle：

希望你能帮助我。

我有项目,Kotlin我已经将Android Studio更新到2.3.3和gradle3.3并将工具构建到25.3.1.在构建期间,我收到此错误:

我想在选择位置时获取完整地址。这是我的场景的一个例子。

当我选择 Uttara 时，如果我应用 place.getName()，我只会得到 Uttara。如果我申请 place.getAddress()，我只会得到孟加拉国 Uttara。我如何才能获得孟加拉国达卡省达卡 Uttara？请各位大侠帮忙......

这是我的代码片段：

 PlaceAutocompleteFragment places= (PlaceAutocompleteFragment)
                getFragmentManager().findFragmentById(R.id.place_autocomplete_fragment_pick);
        LinearLayout ll = (LinearLayout) places.getView().findViewById(R.id.place_autocomplete_fragment_pick);
        ll.setPadding(-7,-7,-7,-7);
        etPickPlace = (EditText)places.getView().findViewById(R.id.place_autocomplete_search_input);
        etPickPlace.setTextColor(getResources().getColor(R.color.colorPrimaryDark));
        etPickPlace.setTextSize(18.0f);
        AutocompleteFilter typeFilter = new AutocompleteFilter.Builder()
                .setCountry("BD")
                .build();

        places.setFilter(typeFilter);
        places.setOnPlaceSelectedListener(new PlaceSelectionListener() {
            @Override
            public void onPlaceSelected(Place place) {
                //Here I want to get the full pick up address
                pickAddress = place.getAddress().toString();
              //  Toast.makeText(getApplicationContext(),place.getName(),Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onError(Status status) {
                Toast.makeText(getApplicationContext(),status.toString(), Toast.LENGTH_SHORT).show();

            }

        });

我想这样强调下微调
