我在抽屉导航中有一些抽屉项目。单击第一项(汽车旅馆)时,它会转到具有汽车旅馆列表的 Activity 。它们中的每一个都包裹在 cardView 中。我已经实现了 cardView 的点击,当它被点击时,它应该用一个 fragment 替换线性布局。但它没有反应。这是代码:Motels.java(包含汽车旅馆列表的 Activity ):

package com.example.sabudaniel61.ktdc;

import android.content.Context;
import android.support.v4.app.FragmentTransaction;

import android.os.Bundle;
import android.support.v4.app.FragmentManager;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.CardView;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.LinearLayout;



/**

*/
public class Motels extends AppCompatActivity{

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.motels);

CardView cardView1=(CardView) findViewById(R.id.cardView1);
cardView1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {

FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction transaction = fragmentManager.beginTransaction();
MotelKttrk motelKttrk = new MotelKttrk();
transaction.replace(R.id.linearmotel, motelKttrk);
transaction.commit();


}
});
}
}

motels.xml(汽车旅馆布局 list ):单击其中一个列表时,它应该用 id @+id/linearmotel 替换 LinearLayout

最佳答案

尝试在 xml 中将 linearmotel 从 LinearLayout 更改为 FrameLayout 并定义宽度和高度。

<FrameLayout
android:layout_width="match_parent" // change as per your requirement
android:layout_height="match_parent" // change as per your requirement
android:id="@+id/linearmotel">
