android自定义Dialog菜鸟级讲解

PopuWindowHealthRecord.this.dismiss();

PopuWindowHealthRecord extends Dialog

dialog设置自定义风格（样式）

public PopuWindowHealthRecord(Context context) {
    super(context, R.style.HealthDialog);

//设置布局（完美实现各种布局）dialog和activity就基本差不多了
    setContentView(R.layout.popuwindow_health_record);
    this.inflater = LayoutInflater.from(context);

dialog自定义风格values下的stytle。xml中写

<style name="HealthDialog" parent="android:style/Theme.Dialog">
    <item name="android:windowNoTitle">true</item>

    <item name="android:windowBackground">@android:color/background_light</item>
    <item name="android:colorBackgroundCacheHint">@null</item>
    <item name="android:windowIsTranslucent">true</item>
</style>

创建dialog（实例化）

//我的健康档案
tvHealthRecord.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Toast.makeText(contentView.getContext(), "测试点击", Toast.LENGTH_LONG).show();
        //创建POP窗口
        PopuWindowHealthRecord popuWindowHealthRecord = new PopuWindowHealthRecord(context);
        //设置布局属性用的parm
        WindowManager.LayoutParams parm = new WindowManager.LayoutParams();
        // 获取屏幕密度
        DisplayMetrics dm = new DisplayMetrics();
        dm = context.getResources().getDisplayMetrics();
        //设置屏幕宽高
        parm.width =dm.widthPixels/2;
        parm.height = dm.heightPixels;
        //设置dialog位置
        //这个设置是紧靠左边
        parm.x = -parm.width;
        parm.y = 0;
        popuWindowHealthRecord.getWindow().setAttributes(parm);
        //设置是否点击dialog外的地方，dialog消失
        popuWindowHealthRecord.setCanceledOnTouchOutside(false);
        popuWindowHealthRecord.show();
