Question

我正在使用Android，我有一个菜单选项，我希望该选项在我点击它时启动一个新活动，但是当我尝试实现启动活动时，我总是有一个强制关闭这里是我的代码：

@Override
public boolean onOptionsItemSelected(MenuItem item)
{
    switch (item.getItemId()) 
    {
        case R.id.tentang :
            startActivity(new Intent(getApplicationContext(), about.class));
            finish();
            return true;
        default : 
            return super.onContextItemSelected(item);
    }
}

你有什么想法解决它吗？

编辑：这个论坛的一些人要我展示我的logcat，这里是：

谢谢大家，你真是太棒了！现在我已经完成了这个问题。

Answer 1

试试这个

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    //Toast.makeText(this, "You pressed the icon!", Toast.LENGTH_LONG).show();
    Intent i = new Intent(MainActivity.this, SecondActivity.class);
    startActivity(i);

    return true;
}

Answer 2

在return语句中更改：

super.onContextItemSelected(item);

为：

super.onOptionsItemSelected(item);

我修改了你的方法：

@Override
public boolean onOptionsItemSelected(MenuItem item)
{
    switch (item.getItemId()) 
    {
        case R.id.tentang :
            startActivity(new Intent(getApplicationContext(), about.class));
            return true;
    }
    return super.onOptionsItemSelected(item);
}

Answer 3

尝试删除finish（）。

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // TODO Auto-generated method stub
    Toast.makeText(this, "selected ", 20).show();
    Intent intent_details = new Intent(this, about.class);
    startActivity(intent_details);
    return true;
}

Answer 4

我猜你没有将你的Activity添加到AndroidManifest.xml。假设您的Activity是com.yourdomain.About。将这些行添加到AndroidManifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.yourdomain"
    android:versionCode="1"
    android:versionName="1.0">

<uses-sdk android:minSdkVersion="7" />

<application .......

<activity
    android:name=".About"
    android:label="About!" >
</activity>

我希望这有帮助！

Answer 5

试试这样：

@Override
public boolean onOptionsItemSelected(MenuItem item){

    switch(item.getItemId()){
case R.id.tentang : 
newActivity();

};  


    return super.onOptionsItemSelected(item);
}    

    private void newActivity(){

        Intent i=new Intent();
        i.setClass(Activity.this, about.class);
        startActivity(i);   
    }
