Android应用之间的跳转以及参数的传递

Posted 2022-11-06 一支向前

1. /**
2. * @param v 设置按钮点击事件
3. */
4. @Override
5. public void onClick(View v)
6. super.onClick(v);
7. switch (v.getId())
8. case R.id.tv_content://跳转点击事件
9. //ComponentName 做跳转，第一个参数传递是B应用的包名，第二个参数传递的是你所需要跳转到B应用的界面
10. try
11. ComponentName componentName = new ComponentName("com.example.intentActivity2", "com.example.intentActivity2.SecondActivity");
12. Intent intent = new Intent();
13. // Intent intent = new Intent("chroya.foo");
14. Bundle bundle = new Bundle();
15. bundle.putString("args", "我就是跳转过来的");
16. intent.putExtras(bundle);
17. intent.setComponent(componentName);
18. startActivity(intent);
19. catch (ActivityNotFoundException e)
20. //判断是否安装B应用，提供下载链接
21. NameToast.show(mContext, "请下载----" + "com.example.intentActivity2");
22. e.printStackTrace();
24. break;

1. public class MainActivity extends Activity
2. private TextView tv_content;
4. @Override
5. protected void onCreate(Bundle savedInstanceState)
6. super.onCreate(savedInstanceState);
7. setContentView(R.layout.main);
8. this.tv_content = (TextView) this.findViewById(R.id.tv_content);
9. Intent intent = getIntent();
10. String value = intent.getStringExtra("args");
11. ToastUtils.show(value);
