自定义View组合模式

attrs.xml:

<?xml version="1.0" encoding="utf-8"?><resources>    <declare-styleable name="ImageText">        <attr name="src" format="reference|color" />        <attr name="imageWidth" format="dimension" />        <attr name="imageHeight" format="dimension" />        <attr name="textSize" format="dimension" />        <attr name="text" format="string" />    declare-styleable>resources>

组合控件的布局view_image_text.xml：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:orientation="vertical"    android:gravity="center_horizontal" >    <ImageView        android:id="@+id/iv_image"        android:layout_width="wrap_content"        android:layout_height="wrap_content" />    <TextView        android:id="@+id/tv_text"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:textColor="@drawable/selector_student_text" />LinearLayout>

activity_main.xml:

"http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    xmlns:it="http://schemas.android.com/apk/res-auto">    id="@+id/it_test"        it:src="@mipmap/ic_launcher"        it:imageWidth="20dp"        it:imageHeight="20dp"        it:text="hello"        android:layout_width="wrap_content"        android:layout_height="wrap_content"/>

drawable

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">    <item android:color="@android:color/holo_blue_dark" android:state_selected="true"/>    <item android:color="@android:color/holo_blue_dark" android:state_checked="true"/>    <item android:color="@android:color/holo_blue_dark" android:state_pressed="true"/>    <item android:color="@android:color/darker_gray"/>selector>

MainActivity.java

package com.itant.customedview;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Toast;public class MainActivity extends Activity implements OnClickListener {    private ImageText it_test;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        it_test = (ImageText) findViewById(R.id.it_test);        it_test.setOnClickListener(this);    }    @Override    public void onClick(View v) {        // TODO Auto-generated method stub        Toast.makeText(this, "click", Toast.LENGTH_SHORT).show();    }}

自定义控件：

package com.itant.customedview;import android.content.Context;import android.content.res.TypedArray;import android.util.AttributeSet;import android.view.LayoutInflater;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.TextView;public class ImageText extends LinearLayout {    private TextView textView;    public ImageText(Context context, AttributeSet attrs) {        super(context, attrs);        // TODO Auto-generated constructor stub        LayoutInflater.from(context).inflate(R.layout.view_image_text, this);        ImageView imageView = (ImageView) findViewById(R.id.iv_image);        textView = (TextView) findViewById(R.id.tv_text);        TypedArray typedArray = context.obtainStyledAttributes(attrs, R.styleable.ImageText);        int imageResource = typedArray.getResourceId(R.styleable.ImageText_src, 0);        int imageWidth = UIUtils.dip2px(context, typedArray.getDimension(R.styleable.ImageText_imageWidth, 40));        int imageHeight = UIUtils.dip2px(context, typedArray.getDimension(R.styleable.ImageText_imageHeight, 40));        float textSize = typedArray.getDimension(R.styleable.ImageText_textSize, 12);        String text = typedArray.getString(R.styleable.ImageText_text);        typedArray.recycle();        imageView.setBackgroundResource(imageResource);        LayoutParams params = new LayoutParams(imageWidth, imageHeight);        imageView.setLayoutParams(params);        textView.setTextSize(textSize);        textView.setText(text);    }    /*    @Override    public boolean onTouchEvent(MotionEvent event) {        // TODO Auto-generated method stub        switch (event.getAction()) {        case MotionEvent.ACTION_DOWN:            textView.setTextColor(getResources().getColor(R.color.red));            break;        case MotionEvent.ACTION_UP:            textView.setTextColor(getResources().getColor(R.color.gray));            break;        default:            break;        }        //performClick();        return super.onTouchEvent(event);    }*/}
