android 通过子线程跳转activity并传递内容

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
