一、线性布局LinearLayout

线性布局LinearLayout
相对布局RelativeLayout

layout_width : match_parent匹配父控件 wrap_content根据文字内容匹配

二、TextView

常用属性设置

<TextView
            android:id="@+id/textViewOne"
            android:layout_width="100dp"
            android:layout_height="wrap_content"
            android:text="Hello Albert"
            android:maxLines="1" 最大行数
            android:ellipsize="end" 最后显示为...
            android:textSize="20sp" 字体大小
            android:drawableRight="@drawable/awg_pic_tx_run_playing" 在文字右侧插入图片
            android:layout_marginLeft="@dimen/dp_20"
            android:textColor="@color/red"/>


package com.rigol.station.generator.awg;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.graphics.Paint;
import android.os.Bundle;
import android.view.WindowManager;
import androidx.annotation.Nullable;
import com.rigol.station.generator.SplashActivity;
import com.rigol.station.generator.common.base.BaseActivity;
import com.rigol.station.generator.databinding.ActivityAlbertTestBinding;
public class AwgTestActivity extends BaseActivity
{
    private ActivityAlbertTestBinding mBinding;
    @Override protected void onCreate(@Nullable Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        //这句代码是固定的
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
        //创建Binding实例
        mBinding = ActivityAlbertTestBinding.inflate(getLayoutInflater());
        //设置上下文内容（Binding的View)
        setContentView(mBinding.getRoot());
        //设置TextView文本有下划线
        mBinding.textViewOne.getPaint().setFlags(Paint.STRIKE_THRU_TEXT_FLAG);
        //去除锯齿
        mBinding.textViewOne.getPaint().setAntiAlias(true);
        //Button的点击事件
        mBinding.TestButton.setOnClickListener(v->{
            //弹框
            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setTitle("AWG");
            builder.setMessage("AWG交互体验测试");
            builder.setPositiveButton("Good", new DialogInterface.OnClickListener()
            {
                @Override public void onClick(DialogInterface dialog, int which)
                {
                }
            });
            AlertDialog dialog = builder.create();
            dialog.show();
            //界面跳转
            Intent intent = new Intent(this, SplashActivity.class);
            startActivity(intent);
        });
    }
}

跑马灯效果

 <TextView
            android:id="@+id/textViewTwo"
            android:layout_width="@dimen/dp_80"
            android:layout_height="wrap_content"
            android:text="Hello Albert Hello Albert Hello Albert Hello Albert Hello Albert"
            android:singleLine="true"
            android:ellipsize="marquee"
            android:marqueeRepeatLimit="marquee_forever"
            android:focusable="true"
            android:focusableInTouchMode="true"
            android:textSize="20sp"
            android:layout_marginLeft="@dimen/dp_20"
            android:textColor="@color/red"/>

三、Button

常用属性

layout_below = “@id/btn_1 在btn_1的下方

自定义Button样式

在res-drawable下面添加Drawable Resource File

增加代码:

最外面的形状为方形,solid实心颜色为yellow,corners圆角为100dp
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="@color/yellow"/>
    <corners android:radius="@dimen/dp_100"/>
</shape>

虚线框stroke
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke
        android:width="1dp"
        android:color="#FF9900"/>
    <corners android:radius="@dimen/dp_20"/>
</shape>
