新建一个FirstAvtivity.java

import android.app.Activity;
    import android.content.Intent;
    import android.os.Bundle;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.Button;
    
    public class FirstActivity extends Activity { 
        private Button myButton;
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
    
            myButton = (Button) findViewById(R.id.myButton);
            myButton.setOnClickListener(new OnClickListener() {
    
                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    Intent intent = new Intent();
                    //Intent传递参数
                    intent.putExtra("testIntent", "123");
                    intent.setClass(FirstActivity.this, SecondActivity.class);
                    FirstActivity.this.startActivity(intent);
                }
            });
        }
    }

新建第二个SecondActivity.java

import android.app.Activity;
    import android.content.Intent;
    import android.os.Bundle;
    import android.widget.TextView;
    
    public class SecondActivity extends Activity{ 
        private TextView myTextView;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            // TODO Auto-generated method stub
            super.onCreate(savedInstanceState);
            setContentView(R.layout.other);
            //使用Intent对象得到FirstActivity传递来的参数
            Intent intent = getIntent();
            String value = intent.getStringExtra("testIntent");
    
            myTextView = (TextView) findViewById(R.id.myTextView);
            myTextView.setText(value);
        }
    }
