android 获取汉字拼音

由于前段时间项目需要，研究了下android各个版本中的汉字转拼音方法。

虽然Android系统本身自带有有将汉字转化为英文拼音的类和方法， 但是还没有对外开放接口， 需要把代码copy到项目中。其类为HanziToPinyin.Java，主要是在联系人应用中用到，但是在android中4.4版本（包含）和4.4之下的版本方法不一样。

直接上代码

android4.4之后的方法：

由于4.4之后需要用到so文件，所以需要新建一个与系统一样的包名libcore.icu,里面新建Transliterator.java类:

package libcore.icu;

/**
 * Exposes icu4c's Transliterator.
 */
public final class Transliterator {
    private long peer;

    /**
     * Creates a new Transliterator for the given id.
     */
    public Transliterator(String id) {
        peer = create(id);
    }

    @Override
    protected synchronized void finalize() throws Throwable {
        try {
            destroy(peer);
            peer = 0;
        } finally {
            super.finalize();
        }
    }

    /**
     * Returns the ids of all known transliterators.
     */
    public static native String[] getAvailableIDs();

    /**
     * Transliterates the specified string.
     */
    public String transliterate(String s) {
        return transliterate(peer, s);
    }

    private static native long create(String id);

    private static native void destroy(long peer);

    private static native String transliterate(long peer, String s);
}
