Wie zeige ich Text auf `PhotoView` an?

Question

In meiner Anwendung zeige ich ein Bild im Vollbildmodus (was eigentlich eine neue Aktivität ist) unter Verwendung der Bibliothek PhotoView. Das Beispielbild ist unten, also muss der Text genau so angezeigt werden.

ich den XML-Code geschrieben haben, überprüfen Sie bitte unter

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/activity_view_full_screen_image" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:paddingBottom="@dimen/activity_vertical_margin" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin" 
    tools:context="com.example.theace.fullscreen.ViewFullScreenImage" 
    android:orientation="vertical"> 

     <LinearLayout 
      android:id="@+id/li1" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:orientation="vertical"> 

       <com.github.chrisbanes.photoview.PhotoView 
        android:id="@+id/photo_view" 
        android:layout_width="match_parent" 
        android:layout_centerInParent="true" 
        android:layout_height="match_parent" 
        android:layout_marginBottom="40dp" /> 

       <TextView 
        android:layout_width="match_parent" 
        android:layout_height="30dp" 
        android:layout_marginBottom="10dp" 
        android:textColor="@android:color/white" 
        android:id="@+id/tv1"/> 


     </LinearLayout> 


</LinearLayout> 

Unten ist mein zugehörige Java-Code

package com.example.theace.fullscreen; 

import android.graphics.Color; 
import android.net.Uri; 
import android.support.v4.app.NavUtils; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.MenuItem; 
import android.view.Window; 
import android.widget.LinearLayout; 
import android.widget.RelativeLayout; 
import android.widget.TextView; 
import com.github.chrisbanes.photoview.PhotoView; 
import com.squareup.picasso.Picasso; 

public class ViewFullScreenImage extends AppCompatActivity { 

    RelativeLayout li1; 
    TextView textView; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     supportRequestWindowFeature(Window.FEATURE_ACTION_BAR_OVERLAY); 
     this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
     setContentView(R.layout.activity_view_full_screen_image); 
     li1 = (RelativeLayout) findViewById(R.id.activity_view_full_screen_image); 
     li1.setBackgroundColor(Color.BLACK); 
     getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
     textView = (TextView)findViewById(R.id.tv1); 

     loadImage(); 
    } 

    public void loadImage(){ 

     Uri imageUrl = Uri.parse("https://s-media-cache-ak0.pinimg.com/736x/39/c7/64/39c764abd350c509f76c6362780a3a78--outdoor-portraits-outdoor-portrait-photography.jpg"); 

     PhotoView photoView = (PhotoView) findViewById(R.id.photo_view); 
     Picasso.with(this).load(imageUrl).into(photoView); 
     textView.setText("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec tristique nunc turpis, at congue est molestie a. Etiam nec cursus arcu. Curabitur vestibulum ligula vitae velit rutrum sollicitudin. Phasellus imperdiet ultrices semper. Morbi laoreet magna sit amet mi vulputate pharetra. Proin faucibus maximus massa, sit amet vestibulum elit posuere eget."); 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     switch (item.getItemId()) { 
      case android.R.id.home: 
       NavUtils.navigateUpFromSameTask(this); 
       return true; 
      default: 
       return super.onOptionsItemSelected(item); 
     } 
    } 
} 

Wie kann ich dieses Problem beheben?

Answer 1

einfach den Code unten verwenden

<?xml version="1.0" encoding="utf-8"?> 
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/activity_view_full_screen_image" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context="com.example.theace.fullscreen.ViewFullScreenImage" 
    android:orientation="vertical"> 


     <com.github.chrisbanes.photoview.PhotoView 
      android:id="@+id/photo_view" 
      android:layout_width="match_parent" 
      android:layout_centerInParent="true" 
      android:layout_height="match_parent" 
      android:scaleType="center"/> 

     <TextView 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:layout_marginBottom="10dp" 
      android:layout_alignParentBottom="true" 
      android:textColor="@android:color/white" 
      android:layout_gravity="bottom|center_horizontal" 
      android:id="@+id/tv1"/> 


</FrameLayout> 

Answer 2

versuchen dies Ihr activity_view_full_screen.xml wie diese

Gebrauch machen RelativeLayout und machen Sie Ihre TextView zu android:layout_alignParentBottom="true"

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:id="@+id/activity_view_full_screen_image" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical"> 


<com.github.chrisbanes.photoview.PhotoView 
    android:id="@+id/photo_view" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_centerInParent="true" 
    android:scaleType="fitXY" 
    android:layout_marginBottom="40dp" 
    android:src="@drawable/disha" /> 



    <TextView 
     android:id="@+id/tv1" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginBottom="10dp" 
     android:gravity="center" 
     android:padding="5dp" 
     android:layout_alignParentBottom="true" 
     android:background="#9a080808" 
     android:text="@string/abc" 
     android:textColor="@android:color/white" /> 


</RelativeLayout>
