Question

我正在开发一个关于提供Pokémons信息的Android应用程序。

然而，当在不同设备之间切换时，我遇到了很多麻烦。

在此屏幕截图中

你可以清楚地看到应用程序在Nexus 5X上运行良好，但在Nexus 5上，布局完全混乱（如果你注意到我在每台设备上都有Android API 23）。

我知道这是不同设备的像素密度问题，因为Nexus 5有xxhdpi显示屏，而5X在xhdpi和xxhdpi之间有一种“混合显示”。我知道三星Galaxy S6和华为P9 Lite都有相同的Nexus 5问题。我试图调整每个图像的大小，制作drawable-ldpi，drawable-mdpi ...文件夹，但结果只是Android Studio不再看到我的图片了！＆GT;。＆LT;

请帮帮我，真的不知道该怎么办！

                    pokeDetails.setEnabled(true);
                else

        public void onClick(View view) {
            t1=new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
                public void onInit(int status) {
                    if(status != TextToSpeech.ERROR) {
                        t1.setLanguage(Locale.ITALIAN);
                        t1.speak(toSpeech, TextToSpeech.QUEUE_FLUSH, null);
                    }
                }
            });
        }
    });
}

对不起代码中的所有意大利语评论，感谢您给我的任何帮助！

使用productFlavours可以解决此问题，您可以根据需要编写单独的风格。

示例：

productFlavors {
        phone {

        }
        tablet {

        }
    }
