Android 自定义View

在values/attrs.xml中：

< ?xml version="1.0" encoding="utf-8"?>

< resources>

< declare-styleable name="MyView">

< attr name="textColor" format="color" />

< attr name="textSize" format="dimension" />

< attr name="imgBackground" format="integer" />

< attr name="textPaddingLeft" format="dimension"/>

< attr name="textPaddingTop" format="dimension"/>

< /declare-styleable>

< /resources>

编写MyView.java，继承View

package test.cuntomizedview;

import java.util.Calendar;

import test.cuntomizedview.R;

import android.content.Context;

import android.content.res.TypedArray;

import android.graphics.Canvas;

import android.graphics.Color;

import android.graphics.Paint;

import android.os.SystemClock;

import android.util.AttributeSet;

import android.view.View;

public class MyView extends View {

private Paint mPaint;

private Context mContext;

private String mStr;

public MyView(Context context, AttributeSet attrs) {

super(context, attrs);

mContext = context;

initMyView();

TypedArray params = context.obtainStyledAttributes(attrs,

R.styleable.MyView);

int backgroudId = params.getResourceId(

R.styleable.MyView_imgBackground, 0);

if (backgroudId != 0)

setBackgroundResource(backgroudId);

int textColor = params.getColor(R.styleable.MyView_textColor,

0XFFFFFFFF);

setTextColor(textColor);

float textSize = params.getDimension(R.styleable.MyView_textSize, 36);

setTextSize(textSize);

float paddingLeft = params.getDimension(

R.styleable.MyView_textPaddingLeft, 41);
