Android App常用UI细节

一、文本

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"

    android:text="升级指南"

    android:textSize="@dimen/sp_16"

    android:gravity="center_vertical"

    android:textColor="@color/col_333333"

    android:textStyle="bold"

    android:drawablePadding="@dimen/d_8"

    android:layout_marginLeft="@dimen/d_25"

    android:drawableLeft="@drawable/bg_ebc387_radius_2"

    />

2、自定义曲线

z

3、自定义动画：

private void setAnim(Canvas canvas) {

PathMeasure measure =new PathMeasure(mPath, false);

    float pathLength = measure.getLength();

    PathEffect effect =new DashPathEffect(new float[]{pathLength,

            pathLength}, pathLength - pathLength *mProgress);

    mPaintLine.setPathEffect(effect);

    canvas.drawPath(mPath, mPaintLine);

}

4、圆形拐角效果

paint.setPathEffect(newCornerPathEffect(5));

5、虚线效果

paint.setPathEffect(newDashPathEffect(newfloat[]{30,10,20,10},10));

mPaintShader.setColor(Color.GRAY);mPaintShader.setStrokeWidth(3f);mPaintShader.setStyle(Paint.Style.STROKE);mPathEffect.moveTo(300,400);mPathEffect.lineTo(1200,400);mPaintShader.setPathEffect(new DashPathEffect(new float[]{4, 4}, 0));canvas.drawPath(mPathEffect, mPaintShader);

6、组合

//虚线路径DashPathEffect dashPathEffect = new DashPathEffect(new float[]{30, 10, 20, 10}, 0);//圆角拐点路径CornerPathEffect cornerPathEffect = new CornerPathEffect(10);//合并后的路径ComposePathEffect composePathEffect = newComposePathEffect(dashPathEffect, cornerPathEffect);//设置路径paint.setPathEffect(composePathEffect);

7、点+文本

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"

    android:text="提醒用户评价"

    android:textSize="@dimen/sp_13"

    android:textColor="@color/col_333333"

    android:layout_marginLeft="@dimen/d_25"

    android:paddingTop="@dimen/d_6"

    android:paddingLeft="@dimen/d_20"

    android:drawableLeft="@drawable/bg_ebc387_circle"

    android:drawablePadding="@dimen/d_5"

    />

8、boder圆角边框

    android:shape="rectangle">

   

   

   

9、View动画：DiscoverTopicNew DiscoverTopicNew

private void setupTransition(ViewGroup viewGroup){

    final LayoutTransition transition = new LayoutTransition();

    viewGroup.setLayoutTransition(transition);

    transition.setAnimator(LayoutTransition.APPEARING, transition.getAnimator(LayoutTransition.APPEARING));

    transition.setAnimator(LayoutTransition.DISAPPEARING, transition.getAnimator(LayoutTransition.DISAPPEARING));

    transition.setAnimator(LayoutTransition.CHANGE_APPEARING, transition.getAnimator(LayoutTransition.CHANGE_APPEARING));

    transition.setAnimator(LayoutTransition.CHANGE_DISAPPEARING, transition.getAnimator(LayoutTransition.CHANGE_DISAPPEARING));

}

 public void gotoPreviousAnimator() {

    BaseFragment fragment = getThemes(false);

    if (fragment == null) {

      return;

    }

    topic_container.removeAllViews();

    LayoutTransition mLayoutTransition = new LayoutTransition();

    ObjectAnimator animator =

            ObjectAnimator.ofFloat(null, "translationY", -ScreenUtils.getDisplayHeight() / 2f,

                    0f);

    mLayoutTransition.setDuration(LayoutTransition.APPEARING, 200);

    mLayoutTransition.setAnimator(LayoutTransition.APPEARING, animator);

    topic_container.setLayoutTransition(mLayoutTransition);

    topic_container.addView(mRootViewLay);

    TopicFragmentAdapter adapter = new TopicFragmentAdapter(this);

    adapter.setFragments(fragment);

    viewPager2.setAdapter(adapter);

    statisticBuilder.setFromAction("punch_sign_topic_page:switching_topic")

            .setFrom_action_ext("button_type", "2");

    SoyoungStatistic.getInstance().postStatistic(statisticBuilder.build());

  }

    public void gotoNextAnimator() {

    BaseFragment fragment = getThemes(true);

    if (fragment == null) {

      return;

    }

    topic_container.removeAllViews();

    LayoutTransition mLayoutTransition = new LayoutTransition();

    ObjectAnimator animator = ObjectAnimator.ofFloat(null, "translationY",

            +(ScreenUtils.getDisplayHeight() / 2) + 90, 0f);

    mLayoutTransition.setDuration(LayoutTransition.APPEARING, 200);

    mLayoutTransition.setAnimator(LayoutTransition.APPEARING, animator);

    topic_container.setLayoutTransition(mLayoutTransition);

    topic_container.addView(mRootViewLay);

    TopicFragmentAdapter adapter = new TopicFragmentAdapter(this);

    adapter.setFragments(fragment);

    viewPager2.setAdapter(adapter);

    statisticBuilder.setFromAction("punch_sign_topic_page:switching_topic")

            .setFrom_action_ext("button_type", "1");

    SoyoungStatistic.getInstance().postStatistic(statisticBuilder.build());

  }

10、Canvas 填充

/**

* 是否填充

* @param color

* @param isFill

    */

public void setParame(int color,boolean isFill) {

this.mCenterTextColor = color;

  pointPaint.setStyle(isFill? Paint.Style.FILL:Paint.Style.STROKE);

  invalidate();

}

11、渐变

        android:angle="90"

        android:endColor="#2A8EE3"

        android:startColor="#00000000" />

12、代码动态添加View

for (int i = 0; i < 9; i++) { TextView textView = new TextView(mActivity);

ViewGroup.LayoutParams layoutParams = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 500); textView.setText("" + i);

textView.setTextSize(50); 

 textView.setGravity(Gravity.CENTER); textView.setLayoutParams(layoutParams);

 mRecyclerView.addView(textView);}
