intent用法
1.无参数Activity跳转
- Intent it = new Intent(Activity.Main.this, Activity2.class);
- startActivity(it);
2.向下一个Activity传递数据(使用Bundle和Intent.putExtras)
- Intent it = new Intent(Activity.Main.this, Activity2.class);
- Bundle bundle=new Bundle();
- bundle.putString("name", "This is from MainActivity!");
- it.putExtras(bundle); // it.putExtra(“test”, "shuju”);
- startActivity(it); // startActivityForResult(it,REQUEST_CODE);
对于数据的获取可以采用:
- Bundle bundle=getIntent().getExtras();
- String name=bundle.getString("name");
3.向上一个Activity返回结果(使用setResult,针对startActivityForResult(it,REQUEST_CODE)启动的Activity)
- Intent intent=getIntent();
- Bundle bundle2=new Bundle();
- bundle2.putString("name", "This is from ShowMsg!");
- intent.putExtras(bundle2);
- setResult(RESULT_OK, intent);
4.回调上一个Activity的结果处理函数(onActivityResult)
- @Override
- protected void onActivityResult(int requestCode, int resultCode, Intent data) {
- // TODO Auto-generated method stub
- super.onActivityResult(requestCode, resultCode, data);
- if (requestCode==REQUEST_CODE){
- if(resultCode==RESULT_CANCELED)
- setTitle("cancle");
- else if (resultCode==RESULT_OK) {
- String temp=null;
- Bundle bundle=data.getExtras();
- if(bundle!=null) temp=bundle.getString("name");
- setTitle(temp);
- }
- }
- }

1. 指定act ion 和type
// SIM import
2. 指定act ion, da ta和type
(1)隐式查找type
示例代码:
程序会根据data中的uri去查找匹配的type(必须的)
provider中的getType()
case SIM_PEOPLE_ID:
return “vnd.Android.cursor.item/sim-contact”;
配置文件中的filter设定
AndroidManifest.xml
也可以自己设定type,但只能使用 setDataAndType()
3. 其他设定intent的属性方式
打开其他APK文件的ACTIVITY

路径规划:
1. Uri uri = Uri.parse(“http://maps.google.com/maps?f=d&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en”);
2. Intent it = new Intent(Intent.ACTION_VIEW,URI);
3. startActivity(it);

直接拨号
