在我的应用程序中,我有一个片段的实例ActivityFragment
,它是在按下按钮addActivity
时动态添加的。每个delete_button
中都有一个ActivityFragment
,我在ActivityFragment
类中为此按钮设置了一个onclicklistener。当按下delete_button
时,我想从onclick方法内部移除片段。当我创建ActivityFragment
对象并将其添加到fragment类之外的方法中的活动时,我将如何进行此操作?我应该为.remove()
使用哪个字段?
注意,delete_button
应该只移除它所在片段的实例。
这是我的MainActivity.java
和ActivityFragment
班。addActivity
按钮位于底部:
import android.app.Fragment;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.FragmentActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public static class ActivityFragment extends Fragment {
// @Nullable is used because the method may return a null value
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
final View fragment1 = inflater.inflate(R.layout.activity_fragment, container, false);
Button edit_button = (Button) fragment1.findViewById(R.id.edit_button);
Button delete_button = (Button) fragment1.findViewById(R.id.delete_button);
edit_button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
TextView activityText = (TextView) getView().findViewById(R.id.activity_text);
activityText.setText("success");
}
});
delete_button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
getFragmentManager().beginTransaction()
.remove().commit();
}
});
return fragment1;
}
}
public void addActivity(View view) {
ActivityFragment myFragment = new ActivityFragment();
getFragmentManager().beginTransaction()
.add(R.id.fragment_container, myFragment).commit();
}
}
最佳答案
您可以这样删除片段实例
delete_button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
getFragmentManager().beginTransaction()
.remove(ActivityFragment.this).commit();
}
});
