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
