我需要制作一个使用同一抽屉的Android应用程序。我在网上找到了一个教程,这是我的源代码:

我的AppBaseActivity:

<?xml version="1.0" encoding="utf-8"?>

XML主要活动:

<?xml version="1.0" encoding="utf-8"?>

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="assistance.main.MainActivity">

    <TextView
        android:padding="5dp"
        android:text="Evolution du chiffre d'affaires"
        android:background="@drawable/layout_rubrique_title"
        android:layout_width="match_parent"
        android:textStyle="bold"
        android:textSize="16dp"
        android:layout_height="wrap_content" />

    <com.github.mikephil.charting.charts.CombinedChart

        android:layout_marginLeft="5dp"
        android:layout_marginRight="5dp"
        android:layout_width="match_parent"
        android:layout_height="200dp" />

    <TextView
        android:padding="5dp"
        android:text="Affaires en cours"
        android:background="@drawable/layout_rubrique_title"
        android:layout_width="match_parent"
        android:textStyle="bold"
        android:textSize="16dp"
        android:layout_height="wrap_content" />

    <android.support.v7.widget.RecyclerView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="vertical"
        android:id="@+id/opportunites" />

</LinearLayout>

package assistance.main;

import android.graphics.Color;
import android.os.Bundle;
import android.support.v4.content.ContextCompat;

import android.support.v7.widget.RecyclerView;

import assistance.R;
import assistance.utils.AppBaseActivity;

public class MainActivity extends AppBaseActivity {

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

}

最后是XML搜索活动:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/content_search"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="assistance.main.SearchActivity" >

    <ScrollView
        android:id="@+id/seaRecords"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <android.support.v7.widget.RecyclerView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:scrollbars="vertical"
            android:id="@+id/seaResultats" />
    </ScrollView>

</RelativeLayout>

和java搜索活动:

package assistance.main;

import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.KeyEvent;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.EditText;

import assistance.R;
import assistance.utils.AppBaseActivity;

import java.util.ArrayList;

public class SearchActivity extends AppBaseActivity {

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

}

我在每个活动上都有抽屉,但当我从主活动打开另一个活动时,我有一个问题:在主活动的framelayout中添加的所有元素都留在屏幕上,在新元素之前。。。

有人帮我吗?

Main activity:

Search activity:

不要重写setContentView()方法。相反,创建一个不同的方法来加载视图。

public void addView(int layoutResID){
    if (vue!=null){
        LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
        ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams(
                ViewGroup.LayoutParams.MATCH_PARENT,
                ViewGroup.LayoutParams.MATCH_PARENT
        ); 
        View stubView = inflater.inflate(layoutResID, vue, false);
        vue.addView(stubView, lp);
    } 
}

在主活动和搜索活动中调用方法

@Override 
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    addView(R.layout.content_main);
    //... 
}

编辑:

<include
        layout="@layout/app_bar_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
