groovy寫安卓代碼注意事項:

下載sdk:http://groovy-lang.org/download.html
需要配置:

apply plugin: 'com.android.application'buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:1.3.0' classpath 'org.codehaus.groovy:gradle-groovy-android-plugin:0.3.6' }}apply plugin: 'groovyx.grooid.groovy-android'dependencies { compile 'org.codehaus.groovy:groovy:2.4.3:grooid' compile('org.codehaus.groovy:groovy-json:2.4.3') { transitive = false }}

Gradle: 错误:编码 GBK 的不可映射字符的解決方案:

在项目下的build.gradle下添加以下代码即可解决

tasks.withType(Compile) {
options.encoding = “UTF-8”
}
Gradle2.0+环境下需将Compile改为JavaCompile

tasks.withType(JavaCompile) {
options.encoding = “UTF-8”
}

Mac下批量将GBK转换UTF-8编码

原理:
mac shell
iconv -f GBK -t UTF8 “path">"{ipath.java_gbk}.java”

使用方式:

1.自行编译src 或者直接下载dist中的zg-sa.jar
2.需要引用的第三方的包位于lib文件夹中

DEMO:

?
1
2
3
Analysis analysis = new Analysis();
System.out.println(“1: ” + analysis.parse(“这是一个普通评论”).getCode());
System.out.println(“2: ” + analysis.parse(“中国加油!”).getDisplay());
输出:

1: 0
2: 正面

正面:1
负面:-1
中性:0

android 6.0 ssl3_get_server_key_exchange:BAD_DH_P_LENGTH

出現這個原因是因為:
android自家寫的BoringSSL不在支持openssl的漏洞導致logjam attack

保存fragment狀態

activity裡面這樣寫:

 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); if (savedInstanceState == null) { getSupportFragmentManager().beginTransaction() .add(R.id.contentContainer, MainFragment.newInstance()) .commit(); } }

fragment里面这样写:

Bundle savedState;@Overridepublic void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); // Restore State Here if (!restoreStateFromArguments()) { // First Time running, Initialize something here }}@Overridepublic void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); // Save State Here // 這裡是防止旋轉屏幕是出現的狀態丟失問題 saveStateToArguments();}@Overridepublic void onDestroyView() { super.onDestroyView(); // Save State Here saveStateToArguments();}private void saveStateToArguments() { savedState = saveState(); if (savedState != null) { Bundle b = getArguments(); b.putBundle(“internalSavedViewState8954201239547”, savedState); }}private boolean restoreStateFromArguments() { Bundle b = getArguments(); savedState = b.getBundle(“internalSavedViewState8954201239547”); if (savedState != null) { restoreState(); return true; } return false;}/////////////////////////////////// 取出状态数据/////////////////////////////////private void restoreState() { if (savedState != null) { //比如 //tv1.setText(savedState.getString(“text”)); }}//////////////////////////////// 保存状态数据//////////////////////////////private Bundle saveState() { Bundle state = new Bundle(); // 比如 //state.putString(“text”, tv1.getText().toString()); return state;}
