下面举例添加一个WebViewIntentDemoActivity

第一步：先将java文件导入集合项目中

第二步：创建新的main界面，导入需要增加的Activity界面（记得与前面的命名区分开）

第三步：在集合Activity界面中添加一个新按钮

第四步：在集合的Activity中添加按钮的引用以及跳转功能

（新按钮的引用）

（获取新按钮的引用）

（添加点击跳转）

package com.example.activitycommunication;

import android.app.Activity;
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;
import android.widget.TextView;

public class MainActivity extends Activity {

    private static final int SUBACTIVITY1 = 1;
    private static final int SUBACTIVITY2 = 2;

    TextView textView;
    Button btnBroadcast; // 新按钮的引用
    Button btnIntent;//添加新按钮的引用
    Button btnWebViewIntent;//添加新按钮的引用

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        textView = (TextView) findViewById(R.id.textShow);
        final Button btn1 = (Button) findViewById(R.id.btn1);
        final Button btn2 = (Button) findViewById(R.id.btn2);
        btnBroadcast = (Button) findViewById(R.id.btnBroadcast); // 获取新按钮的引用
        btnIntent = (Button) findViewById(R.id.btnIntent);// 获取新按钮的引用
        btnWebViewIntent = (Button) findViewById(R.id.btnWebViewIntent);// 获取新按钮的引用

        btn1.setOnClickListener(new OnClickListener() {
            public void onClick(View view) {
                Intent intent = new Intent(MainActivity.this, SubActivity1.class);
                startActivityForResult(intent, SUBACTIVITY1);
            }
        });

        btn2.setOnClickListener(new OnClickListener() {
            public void onClick(View view) {
                Intent intent = new Intent(MainActivity.this, SubActivity2.class);
                startActivityForResult(intent, SUBACTIVITY2);
            }
        });

        btnBroadcast.setOnClickListener(new OnClickListener() {
            public void onClick(View view) {
                Intent intent = new Intent(MainActivity.this, BroadcastReceiverDemoActivity.class);
                startActivity(intent); // 启动 BroadcastReceiverDemoActivity
            }
        });

        btnIntent.setOnClickListener(new OnClickListener() {
            public void onClick(View view) {
                Intent intent = new Intent(MainActivity.this, IntentDemoActivity.class);
                startActivity(intent); // 启动 IntentDemoActivity
            }
        });

        btnWebViewIntent.setOnClickListener(new OnClickListener() {
            public void onClick(View view) {
                Intent intent = new Intent(MainActivity.this, WebViewIntentDemoActivity.class);
                startActivity(intent); // 启动 WebViewIntentDemoActivity
            }
        });
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        switch (requestCode) {
            case SUBACTIVITY1:
                if (resultCode == RESULT_OK) {
                    Uri uriData = data.getData();
                    textView.setText(uriData.toString());
                }
                break;
            case SUBACTIVITY2:
                break;
        }
    }
}

第五步：在xml中添加相应配置

然后就可以运行成功啦！
