乾物を開発する
一:Android 15の一般的なグラフライブラリをお勧めします.線形、棒柱状、円グラフ、扇形、レーダー、株、折れ線、散点、計器盤...

       HelloCharts:

二::Retrofit+RxJavaの依存:
     //Okhttpライブラリ    implementation 'com.squareup.okhttp3:okhttp:3.11.0'     implementation 'com.squareup.okhttp3:logging-interceptor:3.8.1'    //Retrofitライブラリ    implementation 'com.squareup.retrofit2:retrofit:2.1.0'     implementation 'com.squareup.retrofit2:adapter-rxjava2:2.2.0'    //RxJava     implementation 'io.reactivex.rxjava2:rxjava:2.0.1'     implementation 'io.reactivex.rxjava2:rxandroid:2.0.1'
 
3:    TextView/string.xmlコールドゲートテクニック:プレースホルダ%1$s、%1$dなどの使い方:
        https://www.jianshu.com/p/e9fd92fd0951
 四:  EditTextには、ソフトキーボードをイジェクトしないカーソルがあります.
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
        try {
            Class cls = EditText.class;
            Method setSoftInputShownOnFocus;
            setSoftInputShownOnFocus = cls.getMethod("setShowSoftInputOnFocus", boolean.class);
            setSoftInputShownOnFocus.setAccessible(true);
            setSoftInputShownOnFocus.invoke(mEditText, false);
        } catch (Exception e) {
            e.printStackTrace();
        }

 
五:花火試験のドロップダウン効果:

六:【Androidコレクション】クールなオープンソース10個をお勧めします.

使用方法:直接呼び出せばいい
eg:(0-250)透明度、0の場合は透明、UItilのargbを設定することでステータスバーの色を調整
 StatusBarUtils.setTranslucentImageHeader(this,250,view);
