如何更改底部导航按钮上的活动点击？
我想在我现有的Android应用程序中使用底部导航栏，但问题是所有屏幕都是活动，是否可以加载活动而不隐藏底部导航栏。
示例： 的 activity_main.xml中
<?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>
这是我的基础活动，
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"?>

我已通过以下方式解决了这个问题：
1.使用底部导航栏创建一个 BaseActivity 。
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
的BaseActivity布局
<LinearLayout
android:layout_width="match_parent"

2.在底部导航点击中要打开的所有活动中扩展BaseActivity，还需要扩展活动布局 例如，我创建了五个样本活动。
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"));
}
}
<强> II] WatchlistActivity
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"));
}
}
<强> 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：请确保您正确处理后退。我没有为后退编写任何代码。
答案 1 :(得分：3)
使用import { Component, OnInit, OnDestroy, ViewChild, Directive, NgModule, ViewContainerRef} from '@angular/core';
import { Router, ActivatedRoute, Params } from '@angular/router';
@Component({
templateUrl: 'modules/sample/template/sample-test.component.html' })
export class SampleTestComponent {
}
，每次加载Activity时都必须声明并初始化BottomBar。
对于您的问题，我的回答是否。
顺便说一句，您可以使用Fragment来帮助您解决这个问题。
学习新事物的时间，兄弟。
修改
您只将activity置于 1 活动中。并Fragment在BottomBar内，而所有其他人在Activity内查看和设置数据。
试试吧！
