c# 程序员学习android（2）登陆界面

上次说的是引导界面本次我们说说登陆界面

android的登陆界面很多。我想做一个类似于qq的但是头像是圆形的这种，下面是样图



我想做成这样的，这里有两个技术难点，一个是这个圆形的图，一个是下面的用户名的输入框的样式

原型图需要用程序截取。下面的输入框要放按钮我们先说圆形的图

截面中调用

<com.example.ineeq.RoundImageView
android:layout_height="60dp"
android:layout_width="60dp"
android:src="@drawable/girl"
android:id="@+id/roundImage_network"/>

上面是头像的界面调用，

下面是一个类，直接界面调用就可以，

package com.example.ineeq;

import com.example.ineeq.R;

import android.app.ActionBar;
import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.FragmentTabHost;

protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub

super.onCreate(savedInstanceState);
//requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main_tabs);

//更改标题处理
ActionBar actionBar = getActionBar();
actionBar.show();

init();

private void init()
{
mTabHost = (FragmentTabHost)this.findViewById(android.R.id.tabhost);
mTabHost.setup(this,getSupportFragmentManager(), R.id.realtabcontent);
mTabHost.getTabWidget().setVisibility(View.GONE);
for(int i=0;i<tabs.length;i++){
//			View tabView = this.getLayoutInflater().inflate(R.layout.tab_indicator, null);
mTabHost.addTab(mTabHost.newTabSpec(tabs[i]).setIndicator(tabs[i]),cls[i], null);
}
m_radioGroup = (RadioGroup) findViewById(R.id.main_radiogroup);
m_radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {

@Override
public void onCheckedChanged(RadioGroup group, int checkedId)
{
switch(checkedId){
case R.id.RadioButton0:
mTabHost.setCurrentTabByTag(tabs[0]);
break;

break;

break;
}
}
});
((RadioButton) m_radioGroup.getChildAt(0)).toggle();
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.options, menu);
return super.onCreateOptionsMenu(menu);
}

@Override
public void onOptionsMenuClosed(Menu menu) {
/**
* 每次菜单被关闭时调用. （菜单被关闭有三种情形，menu按钮被再次点击、back按钮被点击或者用户选择了某一个菜单项） TODO
* Auto-generated method stub
*/
super.onOptionsMenuClosed(menu);
}
}
