我尝试了下面的代码,但仍然没有找到将所有包含的键列在一个包中的方法

Java代码:

private void unpackBundle() {
    // TODO Auto-generated method stub
    Set <String> mBundleKeysSet = this.mBundle.keySet();
    int size = mBundleKeysSet.size();
    Toast.makeText(getApplicationContext(), size+" keys",Toast.LENGTH_LONG).show();
    if ( mBundleKeysSet.iterator().hasNext() ) {
        //here i should display a list of the contained keys
                    //in the bundle
    }
}
private void unpacbundle(){
//TODO自动生成的方法存根
Set mBundleKeysSet=this.mBundle.keySet();
int size=mBundleKeysSet.size();
Toast.makeText(getApplicationContext(),size+“keys”,Toast.LENGTH\u LONG.show();
if(mBundleKeysSet.iterator().hasNext()){
//在这里,我应该显示一个包含键的列表
//束手无策
}
}

事实上,我找到了答案:

private void unpackBundle() {
// TODO Auto-generated method stub
Set <String> mBundleKeysSet = this.mBundle.keySet();
int size = mBundleKeysSet.size();
Toast.makeText(getApplicationContext(), size+" keys",Toast.LENGTH_LONG).show();

toast.makeText(getApplicationContext(), mBundleKeysSet.toString() 
               ,Toast.LENGTH_LONG).show();
private void unpacbundle(){
//TODO自动生成的方法存根
Set mBundleKeysSet=this.mBundle.keySet();
int size=mBundleKeysSet.size();
Toast.makeText(getApplicationContext(),size+“keys”,Toast.LENGTH\u LONG.show();
toast.makeText(getApplicationContext(),mBundleKeysSet.toString())
,Toast.LENGTH_LONG)show();

}
