android – 自定义视图不给边缘

我在一个活动中,我创建了一个自定义视图,我在LinearLayout中动态添加.问题是我无法给我添加的自定义视图之间的余量.

这里是我添加的两个彼此相邻的视图.

Screentshot：

动态创建视图的代码：

private void AddSelectedTagUI(final com.main.Feedify.serializers.Tags tag){

    LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View v = inflater.inflate(R.layout.tags,tags_section_selectedtags,false);

    TextView tagName = (TextView)v.findViewById(R.id.customview_tags_name);
    tagName.setText(tag.getTagName());

    ImageView close_button = (ImageView)v.findViewById(R.id.customview_tags_close);

    close_button.setonClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            RemoveTag(tag.getTagID(),selectedTags);
        }
    });

    RelativeLayout.LayoutParams params =  new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,RelativeLayout.LayoutParams.WRAP_CONTENT);

    tags_section_selectedtags.addView(v,params);


    // cast view to tags and add it in our layout.
    // this will help us find out the tag we wanna delete.

    view_selectedTags.add(v);
    this.UpdateMessage(true);
}

标签.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:orientation="horizontal"
    android:background="@drawable/tags"
    android:padding="5dp"
    android:id="@+id/custom_tag"
    >

    <TextView android:id="@+id/customview_tags_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:layout_marginRight="3dp"
        android:layout_centerVertical="true"
        android:textColor="@android:color/white"
        android:textSize="@dimen/title" />

    <ImageView
        android:id="@+id/customview_tags_close"
        android:layout_width="wrap_content"
        android:layout_marginTop="2dp"
        android:layout_toRightOf="@+id/customview_tags_name"
        android:layout_height="wrap_content"
        android:src="@drawable/close"
        android:layout_marginLeft="3dp"
        android:layout_marginRight="10dp"
        />

</RelativeLayout>

activity_tags.xml

        android:layout_marginTop="15dp"

</RelativeLayout>

自定义标签类：

package com.main.Feedify.custom_views;

import android.app.Activity;
import android.content.Context;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.RelativeLayout;
import android.widget.TextView;

import com.main.Feedify.Feedify_mockup.R;
import com.tokenautocomplete.TokenCompleteTextView;
/**
 * Created by Muazzam on 10/17/2015.
 */
public class Tags extends RelativeLayout{

    private com.main.Feedify.serializers.Tags tag;

    public Tags(Context context,AttributeSet attrs)
    {
        super(context,attrs);
        LayoutInflater inflater = LayoutInflater.from(context);
        inflater.inflate(R.layout.tags,this);
    }

    public void setTag(com.main.Feedify.serializers.Tags t){
        this.tag = t;
    }

    public com.main.Feedify.serializers.Tags getTag(){
        return this.tag;
    }

    @Override
    protected void onLayout(boolean changed,int left,int top,int right,int bottom) {
        MarginLayoutParams margins = MarginLayoutParams.class.cast(getLayoutParams());
        int margin = 5;
        margins.topMargin = 0;
        margins.bottomMargin = 0;
        margins.leftMargin = margin;
        margins.rightMargin = 0;
        setLayoutParams(margins);
    };
}

解决方法

您应该尝试将layout_margin设置为您的XML文件中的RelativeLayout,与填充相同.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:orientation="horizontal"
    android:background="@drawable/tags"
    android:layout_margin="5dp"
    android:padding="5dp"
    android:id="@+id/custom_tag">

    <TextView android:id="@+id/customview_tags_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Beyonce"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="3dp"
        android:layout_centerVertical="true"
        android:textColor="@android:color/white"
        android:textSize="@dimen/title" />

    <ImageView
        android:id="@+id/customview_tags_close"
        android:layout_width="wrap_content"
        android:layout_marginTop="2dp"
        android:layout_toRightOf="@+id/customview_tags_name"
        android:layout_height="wrap_content"
        android:src="@drawable/close"
        android:layout_marginLeft="3dp"
        android:layout_marginRight="10dp" />

</RelativeLayout>
