1.要實現這個效果,用多個控制元件組合起來,要用到自定義控制元件

程式碼實現

1.自己寫一個佈局檔案

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="52dp"
        android:id="@+id/layout_title"
        android:background="#ed4255">

        <TextView
            android:id="@+id/text_title"
            android:ellipsize="marquee"
            android:gravity="center_horizontal|center"
            android:singleLine="true"
            android:textSize="20dp"
            android:textColor="#ffffffff"
            android:text="標題欄"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

        <Button
            android:id="@+id/btn"
            android:drawablePadding="6dp"
            android:ellipsize="end"
            android:gravity="center"
            android:onClick="onClick"
            android:paddingLeft="5dp"
            android:singleLine="true"
            android:text="返回"
            android:textSize="18dp"

            android:layout_width="60dp"
            android:textColor="#ffffffff"
            android:layout_height="match_parent" />

        <Button
            android:layout_alignParentRight="true"
            android:id="@+id/btn1"
            android:drawablePadding="6dp"
            android:ellipsize="end"
            android:gravity="center"
            android:onClick="onClick"
            android:paddingLeft="5dp"
            android:singleLine="true"
            android:text="提交"
            android:textSize="18dp"

            android:layout_width="60dp"
            android:textColor="#ffffffff"
            android:layout_height="match_parent" />
    </RelativeLayout>
 

2.自己一個類繼承RelativeLayout

public class TitleActivity extends RelativeLayout implements View.OnClickListener{
    Context mycon;
    public TitleActivity(Context context) {
        this(context,null);
    }

    public TitleActivity(Context context, AttributeSet attrs) {
        this(context, attrs,0);
    }

    public TitleActivity(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        //初始化佈局
        LayoutInflater inflater=LayoutInflater.from(context);
        //必須依賴父佈局   引數1.自定義佈局檔案 2.父元素3.是否依賴父元素佈局
        View view = inflater.inflate(R.layout.aa, this, true);
        //找到控制元件  通過ID
        Button btn=view.findViewById(R.id.btn);
        Button btn1=view.findViewById(R.id.btn1);
        //設定點選事件
        btn.setOnClickListener(this);
        btn1.setOnClickListener(this);
        //把上下文寫成全域性變數
        mycon=context;
    }
    public void onClick(View v){
        //判讀點選事件
        switch (v.getId()){
            case R.id.btn:
                Toast.makeText(mycon,"返回",Toast.LENGTH_LONG).show();
                 break;
            case R.id.btn1:
                Toast.makeText(mycon,"提交",Toast.LENGTH_LONG).show();
                break;
        }

    }
}
 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.bwie.rikao_4.MainActivity">


    <com.bwie.rikao_4.TitleActivity

</LinearLayout>
