登录界面、AutoUtils 屏幕适配、自定义Edittext(显示密码可见和一键清空)和 TextInputLayout的使用。

  1. 登录界面:

  2. AutoUtils自动屏幕适配:

      • AutoUtils屏幕适配使用的方法 :

        • 1、将AutoUtils类复制到要适配的项目中;

          2、在程序的入口(清单文件filter):
          super.onCreate(savedInstanceState);
          //屏幕适配,这里是以720*1280分辨率为基准的适配
          AutoUtils.setSize(this, false, 720, 1280);

          * 这里我们UI是以1920*1280分辨率做图的,并且是横屏显示:
          AutoUtils.setSize(this, false, 1920, 1280);

          View view=View.inflate(this,R.layout.activity_splash,null);
          AutoUtils.auto(view);
          setContentView(view);

          3、在activity中
          View view=View.inflater(this,R.layout.activity_splash,null);
          AutoUtils.auto(view);//放在加载布局的前面
          setContentView(view);

          4、在碎片中
          View view=View.inflate(context,R.layout.view_layout,null);
          AutoUtils.auto(view);

  3. 自定义Edittext输入显示密码和清空内容:

      • 自定义Edittext步骤:

        • 初始化
        1. 创建InputEdittext类继承Edittext;
        2. 重写两个构造方法,可以使用attrs;在构造中初始化init();
        3. 在res/values创建Attrs定义属性:
          <?xml version="1.0" encoding="utf-8"?><resources>    <declare-styleable name="inputAttrs">        <attr name="closeTogDrawable" format="reference|color"/>        <attr name="passwordTogDrawableOpen" format="reference|color"/>        <attr name="passwordTogDrawableClose" format="reference|color"/>        <attr name="closeTogEnabled" format="boolean"/>        <attr name="passwordTogEnabled" format="boolean"/>    </declare-styleable></resources>
        4. context.obtainSytledAttribute()得到TypedArray对象ta,ta.getDrawble获得对应的属性对象,不要忘记了ta.recycle()方法循环.
        5. Drawble需要判断是否为null并且setBounds设置值边距;
        • onDraw:
          初始化完成现在需要将图片画到画布上;
        1. 我们有三个drawble图片所以需要画三个draw创建三个绘制方法(列:本地保存矩阵,结束修复矩阵):

          1     private void closeDraw(Canvas canvas) {
          2         canvas.save();
          3         canvas.translate(getWidth() - mCloseDrawable.getIntrinsicWidth(), getHeight() / 2 - mCloseDrawable.getIntrinsicHeight() / 2);
          4         if (mCloseDrawable != null) {
          5             mCloseDrawable.draw(canvas);
          6         }
          7         canvas.restore();
          8     }
        2. 在onDraw()方法里,判断是否激活是否length>0,满足条件调用对于的绘制方法;
        • onTouchEvent:
          根据判断MotionEvents的up事件点击的范围做逻辑处理;

          1    if (mCloseEnabled&& event.getX() > getWidth() - mCloseDrawable.getIntrinsicWidth()) {
          3                     setText("");
          4                     return true;
          5                 }
      • 自定义EditText代码:
          1 public class InputEditext extends EditText {
          2     private static final String TAG = "INputEdittext";
          3     private AttributeSet mAttrs;
          4     private Drawable mCloseDrawable;
          5     private Drawable mPasswordTogDrawableOpen;
          6     private Drawable passwordTogDrawableClose;
          7     private boolean mCloseEnabled;
          8     private boolean mPasswordEnabled = false;
          9     private boolean mPasswordVisible = false;
         10
         11     Paint mPaint;
         12     Paint mPaint2;
         13 //    Bitmap clearBtm;
         14 //    Bitmap passwrodBtm1;
         15 //    Bitmap passwrodBtm2;
         16 //    private Drawable mPasswordDrawable2;
         17
         18
         19     public InputEditext(Context context, AttributeSet attrs) {
         20         super(context, attrs);
         21         init(context, attrs);
         22         Log.d(TAG, "InputEditext: " + 2);
         23     }
         24
         25     private void init(Context context, AttributeSet attrs) {
         26         mPaint = getPaint();
         27         mPaint2 = getPaint();
         28         BitmapFactory.Options op = new BitmapFactory.Options();
         29         op.inJustDecodeBounds = true;
         30
         31         if (attrs != null) {
         32             TypedArray ta = context.obtainStyledAttributes(attrs, R.styleable.inputAttrs);

  4. TextInputLayout的使用:

      使用EditText的hint属性,用户在输入的时候hint会消失,用户的体验效果是十分不好的.TextInputLayout的出现就是为了解决这个问题.输入时可以将hint升上去。使用也十分简单:

    1. TextInputLayout是MaterialDesign材料设计需要在build文件里依赖:

      compile ‘com.android.support:design:25.3.1‘
    2. 在editext布局外包一层TextInputLayout就可以了,属性也很简单。
    3. 使用注意:
      mNameUser = usernameWrapper.getEditText().getText().toString();mPassword = passwordWrapper.getEditText().getText().toString();便可以得到String对象。usernameWrapper.setError(getString(R.string.error_username_verify)):可是设置错误提示
      usernameWrapper.setErrorEnabled(false):错误是否启动一个错误的布局,是否重新布局。
      usernameWrapper.setHint(getString(R.string.hint_username)):设置提示;
       
  5. 主界面使用:
