onClickListener on imageview开始新的意图

Question

因此，我试图使用onClickListener将图像从一个活动传递给一个新的活动，但我无法弄清楚如何去做。它的工作原理是，应用程序以列表视图开始，您可以选择一个项目，并打开一个新的活动，显示下面的一些信息和图像。我希望能够点击图片在新的活动中打开它。

我的继承人routeDetails.java这是我想点击图像位于

package com.example.zach.listview; 

import android.content.Intent; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.AdapterView; 
import android.widget.TextView; 

import static com.example.zach.listview.R.id.image; 


public class RouteDetails extends AppCompatActivity { 

TouchImageView routeImage; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_route_details); 

    //back button for route details view 
    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 

    //TextView for route details 
    final TextView routeDetailsView = (TextView) findViewById(R.id.routeDetailsView); 
    routeDetailsView.setText(getIntent().getExtras().getString("route")); 

    //ImageView for route details 
    routeImage = (TouchImageView) findViewById(R.id.routeImage); 
    routeImage.setImageResource(getIntent().getIntExtra("imageResourceId", 0)); 


////////// Trying to pass image to new activity 

    routeImage.setOnClickListener(new View.OnClickListener() { 
     public void onClick(View v) 
     { 
      int imageId = (int) image.getResourceId(i, -1); 

      Intent intent = new Intent(v.getContext(),  FullScreenImage.class); 
      intent.putExtra("imageResourceId", imageId); 
      startActivity(intent); 
     } 

    }); 

//////////// 

} 

//back button for route details view 
@Override 
public boolean onSupportNavigateUp(){ 
    finish(); 
    return true; 
} 

} 

和继承人与它

<?xml version="1.0" encoding="utf-8"?> 

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/scrollView1" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:id="@+id/activity_route_details" 
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.zach.listview.RouteDetails"> 



<TextView 
    android:text="TextView" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:id="@+id/routeDetailsView" 
    android:textSize="18sp" 
    android:textAlignment="center" /> 

<com.example.zach.listview.TouchImageView 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:id="@+id/routeImage" 
    android:scaleType="fitCenter" 
    android:layout_alignParentBottom="true" 
    android:layout_alignParentLeft="true" 
    android:layout_alignParentStart="true" 
    android:adjustViewBounds="false" 
    android:layout_below="@+id/routeDetailsView"/> 

</RelativeLayout> 
</ScrollView> 

我的继承人FullScreenImage.java那张activity_route_details.xml那我想要打开图像

package com.example.zach.listview; 

import android.os.Bundle; 
import android.support.v7.app.AppCompatActivity; 

/** 
* Created by Zach on 11/15/2016. 
*/ 

public class FullScreenImage extends AppCompatActivity { 

TouchImageView routeImage; 

@Override 
protected void onCreate(Bundle saveInstanceState){ 
    super.onCreate(saveInstanceState); 
    setContentView(R.layout.full_screen_image); 

    routeImage = (TouchImageView) findViewById(R.id.fullScreenImageView); 
    routeImage.setImageResource(getIntent().getIntExtra("imageFullScreen",  0)); 
} 



} 

继承人full_scren_image.x毫升去用它

<?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" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 

<com.example.zach.listview.TouchImageView 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    app:srcCompat="@+id/routeImage" 
    android:id="@+id/fullScreenImageView" 
    android:layout_weight="1" /> 
</LinearLayout> 

Answer 1

你在额外投入与关键imageResourceId但你试图把它拉出来用钥匙imageFullScreen。尝试在两个地方使用相同的密钥。

Answer 2

将您的图片用作ByteArray。这对我没有任何问题。在发件人活动的点击收听者中，执行以下操作：

Intent senderint = new Intent(context, receiveractivity.class); 
Bitmap bitmap = drawableToBitmap(view.getBackground()); 
ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
byte[] b = baos.toByteArray(); 
senderint.putExtra("myimage", b); 
startActivity(senderint); 

并在接收者活动中执行以下操作。

private void getImage(){ 
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
View v = null; 
v = inflater.inflate(R.layout.receiverlayout, null); 

ViewGroup vg = (ViewGroup) findViewById(R.id.yourmainlayout); 
Bundle bundle = getIntent().getExtras(); 
byte[] ba = bundle.getByteArray("myimage"); 
Bitmap bm = BitmapFactory.decodeByteArray(ba, 0, ba.length()); 
Drawable dr = new BitmapDrawable(getResources, bm); 
vg.setBackground(dr); 
vg.addView(v, 0, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); 
} 

在您的接收器活动的oncreate方法中调用getImage（）。上下文是您的应用程序上下文。祝你好运:)
