如何定期而不是随机更改 toast 消息。我使用随机字符串来更改 toast 消息。但我想定期（按顺序）更改它

Question

// 这是我的数据库，有 3 个字符串。

public class kelimeVeriTabani {
public String[][] fil = { { "message 1", "first " }, { "message 2", "second" }, { "message 3", "third " },}}

// 这是我的 activity 每 15 秒更改一次 toast 消息。

    public class fil extends Activity { 
    kelimeVeriTabani kelimeVeriTabani = new kelimeVeriTabani();
    .
    .
    .
              TextView text = (TextView)   layout.findViewById(R.id.text);
                    // I set Random but 
                    // I want to regular. I do not find the code

                    Random ran = new Random();
                    int i = ran.nextInt(kelimeVeriTabani.fil.length);
text.setText(kelimeVeriTabani.fil[i][0] + " = " + kelimeVeriTabani.fil[i][1]);

                    toast.show();

你想要什么？

也许是这样的？

public class baglaccalistirici extends Activity {
    static int i=0;
    database database = new database();
    //Random ran = new Random();
    text.setText(database.messages[i][0] + " = " + database.messages[i][1]);
    if(++i==database.messages.length)i=0;
}
