问题描述
我想在现有的android应用中使用底部导航栏，但是问题是所有屏幕都是活动的，是否可以在不隐藏底部导航栏的情况下加载活动.
I want to use bottom navigation bar in my existing android app but the problem is all screen are activity ,is it possible to load activity without hiding the bottom navigation bar.
示例: activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.widget.NestedScrollView
android:id="@+id/myScrollingContent"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Your loooooong scrolling content here. -->
</android.support.v4.widget.NestedScrollView>
<com.roughike.bottombar.BottomBar
android:id="@+id/bottomBar"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_gravity="bottom"
app:bb_tabXmlResource="@xml/bottom_bar"
app:bb_behavior="shy"/>
</android.support.design.widget.CoordinatorLayout>
这是我的基本活动，
MainActivity.java
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
BottomBar bottomBar;
bottomBar = (BottomBar) findViewById(R.id.bottomBar);
bottomBar.setOnTabSelectListener(new OnTabSelectListener() {
@Override
public void onTabSelected(@IdRes int tabId) {
if (tabId == R.id.matching) {
Log.i("matching","matching inside "+tabId);
Intent in=new Intent(getBaseContext(),Main2Activity.class);
startActivity(in);
}else if (tabId == R.id.watchlist) {
Log.i("matching","watchlist inside "+tabId);
Intent in=new Intent(getBaseContext(),Main3Activity.class);
startActivity(in);
}
}
});
}
}
Main2Activity
public class Main2Activity extends MainActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_main2);
NestedScrollView dynamicContent = (NestedScrollView) findViewById(R.id.myScrollingContent);
View wizard = getLayoutInflater().inflate(R.layout.activity_main2, null);
dynamicContent.addView(wizard);
Main3Activity
public class Main3Activity extends MainActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_main3);
NestedScrollView dynamicContent = (NestedScrollView) findViewById(R.id.myScrollingContent);
View wizard = getLayoutInflater().inflate(R.layout.activity_main3, null);
dynamicContent.addView(wizard);
}
}
清单
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.bottom.bottomnavigation">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".Main2Activity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MainActivity" />
<activity android:name=".Main3Activity"></activity>
</application>
</manifest>
推荐答案
我已经通过以下方式解决了这个问题:
I have solved this problem in following way:
1.使用底部导航栏创建一个 BaseActivity .
1.Create one BaseActivity with bottom nav bar.
package com.example.apple.bottomnavbarwithactivity;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.RadioButton;
import android.widget.RadioGroup;
public class BaseActivity extends AppCompatActivity {
RadioGroup radioGroup1;
RadioButton deals;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_base);
radioGroup1=(RadioGroup)findViewById(R.id.radioGroup1);
deals = (RadioButton)findViewById(R.id.deals);
radioGroup1.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener()
{
@Override
public void onCheckedChanged(RadioGroup group, int checkedId)
{
Intent in;
Log.i("matching", "matching inside1 bro" + checkedId);
switch (checkedId)
{
case R.id.matching:
Log.i("matching", "matching inside1 matching" + checkedId);
in=new Intent(getBaseContext(),MatchingActivity.class);
startActivity(in);
overridePendingTransition(0, 0);
break;
case R.id.watchList:
Log.i("matching", "matching inside1 watchlistAdapter" + checkedId);
in = new Intent(getBaseContext(), WatchlistActivity.class);
startActivity(in);
overridePendingTransition(0, 0);
break;
case R.id.rates:
Log.i("matching", "matching inside1 rate" + checkedId);
in = new Intent(getBaseContext(),RatesActivity.class);
startActivity(in);
overridePendingTransition(0, 0);
break;
case R.id.listing:
Log.i("matching", "matching inside1 listing" + checkedId);
in = new Intent(getBaseContext(), ListingActivity.class);
startActivity(in);
overridePendingTransition(0, 0);
break;
case R.id.deals:
Log.i("matching", "matching inside1 deals" + checkedId);
in = new Intent(getBaseContext(), DealsActivity.class);
startActivity(in);
overridePendingTransition(0, 0);
break;
default:
break;
}
}
});
}
}
名为 base_activity.xml
<LinearLayout
android:layout_width="match_parent"
android:layout_height="56dp"

2.在要通过底部导航单击打开的所有活动中扩展BaseActivity，并且还需要增加活动布局 例如，我创建了五个示例活动.
2.extend BaseActivity in all the activity that you want to open on bottom nav click and also need to inflate the activity layouts For example, I have created five sample activity.
i] MatchingActivity.
package com.example.apple.bottomnavbarwithactivity;
import android.graphics.Color;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;
//extends our custom BaseActivity
public class MatchingActivity extends BaseActivity {
LinearLayout dynamicContent,bottonNavBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_matching);
//dynamically include the current activity layout into baseActivity layout.now all the view of baseactivity is accessible in current activity.
dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent);
bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar);
View wizard = getLayoutInflater().inflate(R.layout.activity_matching, null);
dynamicContent.addView(wizard);
//get the reference of RadioGroup.
RadioGroup rg=(RadioGroup)findViewById(R.id.radioGroup1);
RadioButton rb=(RadioButton)findViewById(R.id.matching);
// Change the corresponding icon and text color on nav button click.
rb.setCompoundDrawablesWithIntrinsicBounds( 0,R.drawable.ic_matching_clicked, 0,0);
rb.setTextColor(Color.parseColor("#3F51B5"));
}
}
ii]监视列表活动
package com.example.apple.bottomnavbarwithactivity;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;
public class WatchlistActivity extends AppCompatActivity {
LinearLayout dynamicContent,bottonNavBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_watchlist1);
dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent);
bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar);
View wizard = getLayoutInflater().inflate(R.layout.activity_watchlist1, null);
dynamicContent.addView(wizard);
RadioGroup rg=(RadioGroup)findViewById(R.id.radioGroup1);
RadioButton rb=(RadioButton)findViewById(R.id.watchList);
rb.setCompoundDrawablesWithIntrinsicBounds( 0,R.drawable.favourite_heart_selected, 0,0);
rb.setTextColor(Color.parseColor("#3F51B5"));
}
}
iii] RatesActivity
package com.example.apple.bottomnavbarwithactivity;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;
public class RatesActivity extends BaseActivity {
LinearLayout dynamicContent,bottonNavBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// setContentView(R.layout.activity_rates);
dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent);
bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar);
View wizard = getLayoutInflater().inflate(R.layout.activity_rates, null);
dynamicContent.addView(wizard);
RadioGroup rg=(RadioGroup)findViewById(R.id.radioGroup1);
RadioButton rb=(RadioButton)findViewById(R.id.rates);
rb.setCompoundDrawablesWithIntrinsicBounds( 0,R.drawable.ic_rate_clicked, 0,0);
rb.setTextColor(Color.parseColor("#3F51B5"));
}
}
iv] ListingActivity
package com.example.apple.bottomnavbarwithactivity;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;
public class ListingActivity extends BaseActivity {
LinearLayout dynamicContent,bottonNavBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_listing);
dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent);
bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar);
View wizard = getLayoutInflater().inflate(R.layout.activity_listing, null);
dynamicContent.addView(wizard);
RadioGroup rg=(RadioGroup)findViewById(R.id.radioGroup1);
RadioButton rb=(RadioButton)findViewById(R.id.listing);
rb.setCompoundDrawablesWithIntrinsicBounds( 0,R.drawable.ic_listing_clicked, 0,0);
rb.setTextColor(Color.parseColor("#3F51B5"));
}
}
v] DealsActivity
package com.example.apple.bottomnavbarwithactivity;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;
public class DealsActivity extends BaseActivity {
LinearLayout dynamicContent,bottonNavBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_deals);
dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent);
bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar);
View wizard = getLayoutInflater().inflate(R.layout.activity_deals, null);
dynamicContent.addView(wizard);
RadioGroup rg=(RadioGroup)findViewById(R.id.radioGroup1);
RadioButton rb=(RadioButton)findViewById(R.id.deals);
rb.setCompoundDrawablesWithIntrinsicBounds( 0,R.drawable.ic_deals_clicked, 0,0);
rb.setTextColor(Color.parseColor("#3F51B5"));
}
}
注意:请确保您正确处理了后按.我尚未为后按编写任何代码.
Note: make sure that you handle back press properly.I have not written any code for back press.
