Java 找不到片段MyFragment的id 0x的视图
我在调用FragmentManager中的新片段时遇到问题。 当我尝试调用主活动中的片段时,我收到此日志,我不知道为什么:Java 找不到片段MyFragment的id 0x的视图,java,android,android-layout,android-fragments,crash,Java,Android,Android Layout,Android Fragments,Crash,我在调用FragmentManager中的新片段时遇到问题。 当我尝试调用主活动中的片段时,我收到此日志,我不知道为什么: Process: com.robertot.timereport, PID: 31255 java.lang.IllegalArgumentException: No view found for id 0x7f07000a (com.robertot.timereport:id/content_frame) for fragment MyFragment{64c0
Process: com.robertot.timereport, PID: 31255

这是我的主要活动课:
public class MainActivity extends FragmentActivity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//...
}
private void LoadFragment(int position)
{
Fragment frgm = null;
FragmentManager fm = getSupportFragmentManager();
switch(position)
{
case 1:
frgm = new MyFragment();
fragmentTag = "newjob";
break;
}
fm.beginTransaction()
.replace(R.id.content_frame, frgm, fragmentTag) // CRASH HERE
.commit();
}
}
这是我的活动\u主xml:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/content_frame">
</FrameLayout>
我做错了什么
谢谢你的支持 这是创建项目时的android示例:
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment()).commit();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
/**

public static class PlaceholderFragment extends Fragment {
public PlaceholderFragment() {

这肯定会奏效,我希望它能帮助您在R.java中找到解决方案,并搜索这个id:0x7f07000a,它是什么?R.java中有。公共静态最终整数内容\u帧=0x7f07000a;你能展示你的MyFragment类吗?我编辑了主帖…所以,我不认为这是MyFragment的问题…但我不知道可能名称不匹配,或者尝试重新加载项目?不,不起作用…我没有希望。。。我正在尝试所有的解决方案!看我最后的机会:这是荒谬的…不起作用…所以,谢谢你。我感谢你的帮助
