Question

好吧，我已经有了一个AutoCompleteTextView，如果我把它写在字符串上，它已经显示了一些建议。

但我喜欢他记得用户写的内容。请参阅以下示例：

到目前为止，这是我的代码：

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, equipas);
    AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.editText1);
    AutoCompleteTextView textView2 = (AutoCompleteTextView) findViewById(R.id.editText2);
    textView.setAdapter(adapter);
    textView2.setAdapter(adapter);

}

private static final String[] equipas = new String[] {
        //Insert what the user writes!
};

修改

以下是activity.xml中的AutoCompleteTextView：

这是完整的代码：

    //Atribuir o tipo de letra:

    TextView equipum = (TextView)findViewById(R.id.editText1);
    equipum.setTypeface(peint);
    TextView equipdois = (TextView)findViewById(R.id.editText2);
    equipdois.setTypeface(peint);
    //Acaba aqui!

    //Para ver a lista de nomes que já usaram:

equipas需要成为Arraylist

如果您致电adapter.add("value")，那么＆＃34;价值＆＃34;将在您的建议/历史中。
