如何在Android的TextView中显示图像？

Question

我想在TextView中插入一些图像。怎么做？任何想法

Answer 1

您可以创建一个spannableString，并将图像放置在TextView所需的位置。或者你可以使用

ImageSpan is = new ImageSpan(context, resId); 
text.setSpan(is, index, index + strLength, 0); 

Answer 2

做这样的事情。

textView.setCompoundDrawableWithIntrinsicBounds(yourImg, null, null, null); 

Answer 3

ImageSpan is = new ImageSpan(context, R.drawable.arrow); 
SpannableString text = new SpannableString("Lorem ipsum dolor sit amet"); 
text.setSpan(is, 5, 5 + 10, 0); 

Answer 4

化妆custom.xml

 <RelativeLayout 
      xmlns:android="http://schemas.android.com/apk/res/android" 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content"> 
      <ImageView 
       android:id="@+id/thumbnail_view" 
       android:src="@drawable/ic_launcher" 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" /> 

    <TextView android:id="@+id/message_view" 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:layout_toRightOf="@id/thumbnail_view" 
       android:textSize="18sp" 
       android:text="MyText" /> 
     </RelativeLayout> 

然后main.xml中，包括本custom.xml

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
      android:orientation="vertical" 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent" 
      android:gravity="center_horizontal"> 

    <include 
     android:id="@+id/customView" 
     layout="@layout/custom"/> 

      </LinearLayout> 

这是我mainActivity.class

package com.example.test; 


import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.ImageView; 
    import android.widget.TextView; 


    public class MainActivity extends Activity implements OnClickListener { 

    private String TAG = MainActivity.class.getSimpleName(); 
    ImageView img; 
    ImageView img1; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    TextView txt = (TextView)findViewById(R.id.message_view); 
    img = (ImageView) findViewById(R.id.thumbnail_view); 
    img1 = (ImageView) findViewById(R.id.thumbnail_view1); 

    img.setOnClickListener(this); 
    img1.setOnClickListener(this); 

} 
@Override 
public void onClick(View v) { 
    if(v== img){ 
     // do something for img 
    } 
    else if (v== img1){ 
     //do something for img1 
    } 

} 
}

要容易得多可以使用SpannableStringBuilder从API 1

实例：

对于API> = 21

SpannableStringBuilder builder = new SpannableStringBuilder(); 
    builder.append("My string. I ") 
      .append(" ", new ImageSpan(getActivity(), R.drawable.ic_action_heart), 0) 
      .append(" Cree by Dexode"); 

    textView.setText(builder); 

对于API> = 1

SpannableStringBuilder builder = new SpannableStringBuilder(); 
    builder.append("My string. I ").append(" "); 
    builder.setSpan(new ImageSpan(getActivity(), R.drawable.ic_action_heart), 
      builder.length() - 1, builder.length(), 0); 
    builder.append(" Cree by Dexode"); 

    textView.setText(builder);
