[Android]使用到另一個view

在Android中，如果把另一個layout加進來目前的View中，並且使用它，

用法如下：


MainActivity.java

package com.example.flowercatswets.myapplication;

import android.graphics.Color;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.*;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;

public class MainActivity extends ActionBarActivity {

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

        LinearLayout rootLayout=(LinearLayout)findViewById(R.id.root);

        View view;
        LayoutInflater inflater = (LayoutInflater)  getSystemService(LAYOUT_INFLATER_SERVICE);
        view = inflater.inflate(R.layout.childlayout, null);

        TextView  childtext=(TextView)view.findViewById(R.id.text);
        childtext.setText("I am child view");

        ImageView ivColor= (ImageView)view.findViewById(R.id.mycolor);
        ivColor.setBackgroundColor(Color.GREEN);

        rootLayout.addView(view);

    }

}

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/root"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:id="@+id/test"
        android:text="in the main layout"
       />

</LinearLayout>

childlayout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    >
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/text"
        />

    <ImageView
        android:id="@+id/mycolor"
        android:layout_width="100dp"
        android:layout_height="100dp" />
</LinearLayout>

執行結果：
