ntent用法实例
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);
- startActivity(it);
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) {
-
- 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);
- }
- }
- }

发起一个应用程序
ComponentName 两个参数一个是包名 一个是包下的主类
- final Intent intent = new Intent(Intent.ACTION_MAIN, null);
- intent.addCategory(Intent.CATEGORY_LAUNCHER);
- final ComponentName cn = new ComponentName("com.android.settings","com.android.settings.fuelgauge.PowerUsageSummary");
