android利用数据库实现搜索联想功能

在res的xml文件夹下创建searchable.xml

< ?xml version="1.0" encoding="utf-8"? >

< searchable xmlns:android="http://schemas.android.com/apk/res/android"

android:label="@string/search_label"

android:searchSuggestAuthority="search"

android:searchSuggestIntentAction="android.intent.action.VIEW"

>

< /searchable >

结果返回：

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

Intent intent = this.getIntent();

setContentView(R.layout.main);

if (Intent.ACTION_VIEW.equals(intent.getAction())) {

SearchUtil.Word theWord = SearchUtil.getInstance().getMatches(

intent.getDataString().trim().toLowerCase()).get(0);

launchWord(theWord);

finish();

} else {

Button button = (Button) findViewById(R.id.button);

button.setOnTouchListener(new OnTouchListener() {

@Override

public boolean onTouch(View v, MotionEvent event) {

onSearchRequested();

return false;

}

});

}

}

private void launchWord(SearchUtil.Word pavilion) {

Intent next = new Intent();

next.setClass(this, ResultActivty.class);

Bundle bundle = new Bundle();

bundle.putString("word", pavilion.word);

next.putExtras(bundle);

next.putExtras(bundle);

startActivity(next);

}

其中联想的列表还可以实现自定义的列表，需要进一步细化。
