[Android]使用ActivityGroup來切換Activity和Layout

一、效果圖

     

    要求點選底部不同圖片按鈕切換不同的Activity,並在中間顯示Activity對應的ContentView。

二、 實現程式碼

    2.1  layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width
="fill_parent" android:orientation="vertical"
    android:layout_height
="fill_parent">
    
<LinearLayout android:gravity="center_horizontal"
        android:background
="@drawable/myinfor2" android:layout_width="fill_parent"
        android:layout_height
="wrap_content">
        
<TextView android:id="@+id/cust_title" android:textColor="@android:color/white"
            android:textSize
="28sp" android:text="模組1" android:layout_width="wrap_content"
            android:layout_height
="wrap_content"></TextView>
    
</LinearLayout>
    
<!-- 中間動態載入View -->
    
<ScrollView android:measureAllChildren="true" android:id="@+id/containerBody"
        android:layout_weight
="1" android:layout_height="fill_parent"
        android:layout_width
="fill_parent">
    
</ScrollView>
    
<LinearLayout android:background="@android:color/black"
        android:layout_gravity
="bottom" android:orientation="horizontal"
        android:layout_width
="fill_parent" android:layout_height="wrap_content">
        
<!-- 功能模組按鈕1 -->
        
<ImageView android:id="@+id/btnModule1" android:src="@android:drawable/ic_dialog_dialer"
            android:layout_marginLeft
="7dp" android:layout_marginTop="3dp"
            android:layout_marginBottom
="3dp" android:layout_width="wrap_content"
            android:layout_height
="wrap_content" />
        
<!-- 功能模組按鈕2 -->
        
<ImageView android:id="@+id/btnModule2" android:src="@android:drawable/ic_dialog_info"
            android:layout_marginLeft
="7dp" android:layout_marginTop="3dp"
            android:layout_marginBottom
="3dp" android:layout_width="wrap_content"
            android:layout_height
="wrap_content" />
        
<!-- 功能模組按鈕3 -->
        
<ImageView android:id="@+id/btnModule3" android:src="@android:drawable/ic_dialog_alert"
            android:layout_marginLeft
="7dp" android:layout_marginTop="3dp"
            android:layout_marginBottom
="3dp" android:layout_width="wrap_content"
            android:layout_height
="wrap_content" />
    
</LinearLayout>
</LinearLayout>

    2.2  TestView.java

public class TestView extends ActivityGroup {

    
private ScrollView container = null;

    @Override
    
protected void onCreate(Bundle savedInstanceState) {
        
super.onCreate(savedInstanceState);
        
// 隱藏標題欄
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        
// 設定檢視
        setContentView(R.layout.layout);

        container 
= (ScrollView) findViewById(R.id.containerBody);

        
// 模組1
        ImageView btnModule1 = (ImageView) findViewById(R.id.btnModule1);
        btnModule1.setOnClickListener(
new OnClickListener() {
            @Override
            
public void onClick(View v) {
                container.removeAllViews();
                container.addView(getLocalActivityManager().startActivity(
                        
"Module1",
                        
new Intent(TestView.this, ModuleView1.class)
                                .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
                        .getDecorView());
            }
        });

        
// 模組2
        ImageView btnModule2 = (ImageView) findViewById(R.id.btnModule2);
        btnModule2.setOnClickListener(
new OnClickListener() {
            @Override
            
public void onClick(View v) {
                container.removeAllViews();
                container.addView(getLocalActivityManager().startActivity(
                        
"Module2",
                        
new Intent(TestView.this, ModuleView2.class)
                                .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
                        .getDecorView());
            }
        });

        
// 模組3
        ImageView btnModule3 = (ImageView) findViewById(R.id.btnModule3);
        btnModule3.setOnClickListener(
new OnClickListener() {
            @Override
            
public void onClick(View v) {
                container.removeAllViews();
                container.addView(getLocalActivityManager().startActivity(
                        
"Module3",
                        
new Intent(TestView.this, ModuleView3.class)
                                .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
                        .getDecorView());
            }
        });
    }
}

    程式碼說明:

      a).  ModuleView1、ModuleView2 ModuleView3分別繼承自Activity。

      b).  想動態改變標題可以通過cust_title獲取TextView進行設定。
