Android模仿QQ登陆窗口

释放双眼,带上耳机,听听看~!

 

 

今天根据腾讯qq,我们做一个练习,来学习如何制作一个漂亮的布局。首先看一下官方图片

还是一个启动画面,之后进入登录页面,导航页面就不介绍了,大家可以参考微信的导航页面。首先程序进入SplashActivity,就是启动页面,Activity代码如下:

package com.example.imitateqq;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;

public class SplashActivity extends Activity {

private Intent intent;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
startMainAvtivity();
}

private void startMainAvtivity() {
new Handler().postDelayed(new Runnable() {
public void run() {
intent=new Intent(SplashActivity.this,QQ.class);
startActivity(intent);
SplashActivity.this.finish();//结束本Activity
}
}, 1000);//设置执行时间
}
}


xml布局文件就是一个全屏的图片,要注意的是设置android:scaleType ="matrix"这个属性。不然不会全屏


xml version= "1.0" encoding = "utf-8"?>
android:layout_width= "match_parent"
android:layout_height= "match_parent"
android:orientation= "vertical" >
android:layout_width ="match_parent"
android:layout_height ="match_parent"
android:scaleType ="matrix"
android:src ="@drawable/splash" />
LinearLayout>

 

过1秒之后转入登陆页面,从图片我们可以看出,腾讯的UI做的还是相当美观漂亮的,既简洁又不失美观。先分析一下这个登录界面,从整体可以看出,根布局的背景色是蓝色的,而那个QQ 2012 Android其实是一个图片背景色和根布局的背景色一样,这样就不会有视觉偏差。下面就是两个文本框EditText了,注意这里和官方给的不一样,因为后面有一个小箭头,当点击这个箭头时,会在第一个文本框的下面显示已经输入的qq号码,在qq号码的后面还有删除qq信息的按钮。这个地方需要注意一下。再往下就是登陆Button以及那连个“记住密码”和“注册新账号”比较简单,注意位置的安排即可。最后就是最下面的“更多登陆选项”,当点击的时候会向上弹出一些内容,其实就是一个隐藏的布局,当点击上面的时候,使下面隐藏的布局显示。当然也可以使用滑动抽屉来做,但是相对来说比较麻烦。下面看一下xml代码,相信大家就会一路了然。

各个组件的使用没有问题,关键是如何设置他们的属性,来获得一个比较美观的效果,大家可以参考这个例子,来做一下练习,来强化UI的设计。从这个例子中就可以学到很多东西,比如ViwGroup的使用(如何枪套),background的设置,例如同时使用两个Edittext,设置android:background =“@null”设置为空的时候就不会产生间隔了。这个要自己多做设计,时间长了就会有感悟了。最后看一下MainActivity的代码,布局简单

package com.example.imitateqq;

import android.os.Bundle;
import android.app.Activity;
import android.app.Dialog;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;

public class QQ extends Activity implements OnClickListener{

private Button login_Button;
private View moreHideBottomView,input2;
private ImageView more_imageView;
private boolean mShowBottom = false;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_qq);
initView();
}

private void initView() {
login_Button=(Button) findViewById(R.id.buton1);
login_Button.setOnClickListener(this);

moreHideBottomView=findViewById(R.id.morehidebottom);
more_imageView=(ImageView) findViewById(R.id.more_image);

input2=findViewById(R.id.input2);
input2.setOnClickListener( this);
}

public void showBottom(boolean bShow){
if(bShow){
moreHideBottomView.setVisibility(View.GONE);
more_imageView.setImageResource(R.drawable.login_more_up);
mShowBottom = true;
}else{
moreHideBottomView.setVisibility(View.VISIBLE);
more_imageView.setImageResource(R.drawable.login_more);
mShowBottom = false;
}
}

public void onClick(View v) {
switch(v.getId())
{
case R.id.input2:
showBottom(!mShowBottom);
break;
case R.id.buton1:
showRequestDialog();
break;
default:
break;
}
}

private Dialog mDialog = null;
private void showRequestDialog()
{
if (mDialog != null)
{
mDialog.dismiss();
mDialog = null;
}
mDialog = DialogFactory.creatRequestDialog(this, "正在验证账号...");
mDialog.show();
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_qq, menu);
return true;
}
}

 

最后效果如下:
