android 子线程中不能够更新ui已经根深蒂固在我的脑海里,当时也就理所当然的觉得子线程中也是不能够进行界面的跳转的,可是在后来的学习中,发现居然是能够通过子线程来进行activity的跳转时,立刻把我给震惊了.赶紧滚去写代码測试了下.结果真的能够.顿时泪奔.特此记录一下.与君共勉
activity:
package com.example.testchildthreadgootheractivity; import android.app.Activity; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.util.Log; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.TextView; public class MainActivity extends Activity { private Context context; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); context = this; //第一个button,通过主线程跳转activity,并传递内容 findViewById(R.id.btn_go1).setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Log.e("test", "main thread:" + Thread.currentThread().getName() + "id:" + Thread.currentThread().getId()); Intent intent = new Intent(context, OtherActivity.class); // 測试传递字符串 intent.putExtra("hello", "hello im main thread"); startActivity(intent); } }); //第二个button,通过子线程跳转activity,并传递内容 findViewById(R.id.btn_go2).setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { new Thread(new Runnable() { @Override public void run() { Log.e("test", "child thread:" + Thread.currentThread().getName() + "id:" + Thread.currentThread().getId()); Intent intent = new Intent(context, OtherActivity.class); // 測试传递字符串 intent.putExtra("hello", "hello im child thread"); startActivity(intent); } }).start(); } }); } }
測试得出结论.子线程能够进行activity的跳转.以及通过intent传递内容
