Android中Intent的使用（三）

package com.itarchy.demo;

import android.app.Activity;
import android.content.ComponentName;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity {

	private Button btnSendValue;
	private Button btnSendBundle;
	private Button btnCtN;
	private Button btnIntent;
	private Button btnCall;
	private Button btnSendmms;
	private Button btnIinternet;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		// 1、Intent传值:直接的键值对形式
		btnSendValue = (Button) this.findViewById(R.id.btn_send_intent);
		btnSendValue.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {

				// 设置启动源和启动目标
				Intent intent = new Intent(MainActivity.this,
						IntentActivity.class);
				// Intent绑定数据
				intent.putExtra("Name", "猪");
				intent.putExtra("Age", 5);
				// 启动Activity
				startActivity(intent);

			}
		});

		// 2、通过Bundle对象封装数据：
		btnSendBundle = (Button) this.findViewById(R.id.btn_send_bundle);
		btnSendBundle.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				// 设置启动源和启动目标
				Intent intent = new Intent(MainActivity.this,
						BundleActivity.class);
				// 新建Bundle对象
				Bundle bundle = new Bundle();
				bundle.putString("Name", "猫");
				bundle.putInt("Age", 3);
				intent.putExtra("toBundle", bundle);
				// 启动Activity
				startActivity(intent);

			}
		});

		// 3、通过ComponentName启动Activity：
		btnCtN = (Button) this.findViewById(R.id.btn_send_ctn);
		btnCtN.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				// 设置启动源和启动目标
				Intent intent = new Intent();
				ComponentName cn = new ComponentName(MainActivity.this,
						CtnActivity.class);
				intent.setComponent(cn);
				// 启动Activity
				startActivity(intent);

			}
		});

		// 4、隐式Intent
		btnIntent = (Button) this.findViewById(R.id.btn_intent);
		btnIntent.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				// 设置启动源和启动目标
				Intent intent = new Intent();
				intent.setAction("com.demo");
				// 启动Activity
				startActivity(intent);

			}
		});

		// 5、:系统内置的Intent"实现拨打电话
		btnCall = (Button) this.findViewById(R.id.btn_call);
		btnCall.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				Intent intent = new Intent();
				intent.setAction(Intent.ACTION_DIAL); // 隐式Intent
				// ACTION_DIAL ACTION_CALL
				Uri uri = Uri.parse("tel:13313433672");
				intent.setData(uri);
				startActivity(intent);

			}
		});

		// 6、:系统内置的Intent"实现发送信息
		btnSendmms = (Button) this.findViewById(R.id.btn_sendmms);
		btnSendmms.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				Uri uri = Uri.parse("tel:13720012546");
				Intent it = new Intent(Intent.ACTION_VIEW, uri);
				it.putExtra("sms_body", "The SMS text");
				it.setType("vnd.android-dir/mms-sms");
				startActivity(it);
			}
		});

		// 7、:系统内置的Intent"实现访问网页
		btnIinternet = (Button) this.findViewById(R.id.btn_internet);
		btnIinternet.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				// 访问网页
				Intent intent = new Intent();
				intent.setAction(Intent.ACTION_VIEW);
				Uri uri = Uri.parse("http://www.baidu.com");
				intent.setData(uri);
				startActivity(intent);

			}
		});

	}
