android – 如何解决“找不到处理Intent的活动”错误

概述android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.android.suven.Create_memo } 我只是想从一个活动转到另一个活动,但它给了我这个错误. 我的主要活动代码如下 @Overridepublic void onCreate(Bundle savedIn

androID.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.androID.suven.Create_memo }

我只是想从一个活动转到另一个活动,但它给了我这个错误.

我的主要活动代码如下

@OverrIDepublic voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentVIEw(R.layout.main);    btn1 = (button)findVIEwByID(R.ID.button1);    btn1.setonClickListener(new VIEw.OnClickListener() {        public voID onClick(VIEw v)         {            try            {                Intent i=new Intent("com.androID.suven.Create_memo");            startActivity(i);            }            catch ( ActivityNotFoundException e) {                e.printstacktrace();            }        }    });      btn2 = (button)findVIEwByID(R.ID.button2);    btn2.setonClickListener(new VIEw.OnClickListener() {        public voID onClick(VIEw v)         {            try            {                Intent i=new Intent("com.androID.suven.Create_memo");            startActivity(i);            }            catch ( ActivityNotFoundException e) {                e.printstacktrace();            }    });            }}

我的logcat是这样的：

解决方法 在你的代码行中

Intent i=new Intent("com.androID.suven.Create_memo");

“com.androID.suven.Create_memo”被视为ACTION.

相反,你必须把

Intent i=new Intent(YourCurrentAivityname.this,Create_memo.class);

还放

<activity            androID:name=".Create_memo" >        </activity>

在AndroIDManifest.xml文件中.
