package lab.sodino.customtoast; import lab.sodino.util.SodinoOut; import android.content.Context; import android.os.Handler; import android.widget.Toast; /**设计原理：在Toast显示消失之前，再次调用Toast.show()进行接力。*/ public class CustomToast { /** 用于测试 */ private int showCount = 1; private Toast toast = null; private Context context; private Handler handler = null; private Runnable toastThread = new Runnable() { public void run() { // 递增的count明显地表明是不断运行新的Toast.show()的结果。 toast.setText(String.valueOf(showCount++) + "CustomToast"); toast.show(); // 3.3秒后再度重启，设为4s的话将会看到Toast是断断续续地显示着的。 handler.postDelayed(toastThread, 3300); } }; public CustomToast(Context context) { this.context = context; handler = new Handler(this.context.getMainLooper()); toast = Toast.makeText(this.context, "", Toast.LENGTH_LONG); } public void setText(String text) { toast.setText(text); } public void showToast(final long length) { handler.post(toastThread); SodinoOut.out("Handler post at:" + System.currentTimeMillis()); Thread timeThread = new Thread() { public void run() { SodinoOut.out("TimeThread start at:" + System.currentTimeMillis()); try { Thread.sleep(length); } catch (InterruptedException e) { e.printStackTrace(); } CustomToast.this.stopToast(); SodinoOut .out("Toast canceled at:" + System.currentTimeMillis()); } }; timeThread.start(); } public void stopToast() { // 删除Handler队列中的仍处理等待的消息元素删除 handler.removeCallbacks(toastThread); // 撤掉仍在显示的Toast toast.cancel(); } }
