在我的Android应用程序中,我正在向联系人发送消息..它显示“此处理程序类应该是静态的,否则可能是泄漏”。我的应用程序在移动电话中崩溃,但它正在使用模拟器,我正在给出下面的代码请通过它,如果有人可以提供任何帮助请帮助..
progresshandler = new Handler()
{
public void handleMessage(Message msg)
{
//progressDialog.dismiss();
//Toast.makeText(SendMessagesActivity.this, "Messages Sent",Toast.LENGTH_LONG).show();
new ProgressTask().execute();
}
};
答案 0 :(得分:1)
为避免泄漏,Handler创建扩展Handler类的Custom类,如下所示:
// Handler of incoming messages from clients.
private static class IncomingHandler extends Handler {
private WeakReference<YourActivity> yourActivityWeakReference;
public IncomingHandler(YourActivity yourActivity) {
yourActivityWeakReference = new WeakReference<>(yourActivity);
}
@Override
public void handleMessage(Message message) {
if (yourActivityWeakReference != null) {
YourActivity yourActivity = yourActivityWeakReference.get();
Edited : new ProgressTask().execute();
// switch (message.what) {
// }
}
}
}
创建此类的对象,无论您想在何处使用,如下所示。
private IncomingHandler mPulseHandler;
mPulseHandler = new IncomingHandler(HomeActivity.this);
mPulseHandler.sendEmptyMessage(0);
编辑:
IncomingHandler progresshandler = new IncomingHandler(YourActivity.this);
if (editMessage.getText().toString().length() > 0) {
SendMessagesThread thread = new SendMessagesThread(progresshandler);
thread.start();
// progressDialog.show();
}
编辑:
在您的活动中声明此任务:
private ProgressTask progressTask;
在onCreate()
中创建它的实例progressTask = new ProgressTask();
更改IncomingHandler中的行:
yourActivity.progressTask.execute();
