我想制作一个类似于自定义布局ScreenShot:的应用程序。这是一行,我又像该行添加了100行,这样人们就可以点击编号或其信息(i
)。
但是它显示为:两个按钮重叠。但是我想要两个按钮彼此相邻,就像custom_layout.xml中的那样(您可以看到屏幕截图)。
这是我的custom_layout.xml
:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:id="@+id/button"
android:layout_width="298dp"
android:layout_height="wrap_content"
android:text="Button"
tools:layout_editor_absoluteX="16dp"
tools:layout_editor_absoluteY="87dp" />
<Button
android:id="@+id/button2"
android:layout_width="51dp"
android:layout_height="49dp"
android:text="Button"
tools:layout_editor_absoluteX="317dp"
tools:layout_editor_absoluteY="87dp" />
</android.support.constraint.ConstraintLayout>
这是我的
activity_main.xml
:<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="@+id/listView1"
android:layout_width="162dp"
android:layout_height="424dp"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:layout_marginTop="87dp" />
</RelativeLayout>
</ScrollView>
这是我的
MainActivity.java
:package com.hey.task.attendancesystem;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.ListView;
public class MainActivity extends AppCompatActivity {
Button[] button=new Button[15];
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView listView = (ListView) findViewById(R.id.listView1);
CustomAdapter customAdapter = new CustomAdapter();
//listeyi customlayouttaki şekilde oluşturdum hepsini
listView.setAdapter(customAdapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
}
});
}
class CustomAdapter extends BaseAdapter {
@Override
public int getCount() {
return button.length;
}
@Override
public Object getItem(int i) {
return null;
}
@Override
public long getItemId(int i) {
return 0;
}
@Override
public View getView(int i, View view, ViewGroup viewGroup) {
view = getLayoutInflater().inflate(R.layout.custom_layout,null);
Button button1 = (Button) view.findViewById(R.id.button);
Button button2 = (Button) view.findViewById(R.id.button2);
for (int j = 0;j<15;j++)
button1.setText(i + "");
for (int j = 0;j<15;j++)
button2.setText("i");
return view;
}
}
}
最佳答案
我不知道我是否收到您的问题,但您可以简单地使用LinearLayout进行加权。例如:-
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:orientation="horizontal"
android:weightSum="1">
<Button
android:id="@+id/button_1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight=".5" // or whatever you want
android:background="?android:attr/selectableItemBackground"
android:gravity="center"
android:padding="10dp"
android:text="Title 1" />
<Button
android:id="@+id/button_2"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight=".5" // or whatever you want
android:background="?android:attr/selectableItemBackground"
android:gravity="center"
android:padding="10dp"
android:text="Title 2" />
</LinearLayout>
