Main1Activity、Main2Activity可以互相跳转，但Main1Activity无法向Main2Activity传送数据。
在Main1Activity中直接这样写bundle.putString("snameText", string)，在Main2Activity中可以接收数据。
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.widget.EditText;
public class Main1Activity extends ActionBarActivity {
private Intent intent = new Intent();
private Bundle bundle = new Bundle();//新建Bundle
private EditText snameText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main1);
snameText = (EditText) findViewById(R.id.snameText);
bundle.putString("snameText", snameText.getText().toString());
}
public void confirmMain1(View v) {
intent.setClass(Main1Activity.this, Main2Activity.class);
intent.putExtras(bundle);
startActivity(intent);
}
}
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
public class Main2Activity extends Activity {
private Intent intent = new Intent();
private Bundle bundle = new Bundle();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
bundle = this.getIntent().getExtras();
String snameText = bundle.getString("snameText");
TextView snameView = (TextView) findViewById(R.id.snameView);
snameView.setText(snameView.getText().toString() + snameText.toString());
}
public void returnMain2(View v) {
intent.setClass(Main2Activity.this, Main1Activity.class);
startActivity(intent);
}
}
