Android 简单图片浏览

视图界面很简单，主要就是AndroidManifest的配置。

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.ImageView;
import android.widget.Toast;

public class ImageShowActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ImageView imageView = new ImageView(this);
        setContentView(imageView);

        try {
            imageView.setImageURI(getIntent().getData());
        }catch (Exception ex){
            Toast.makeText(this, "不能打开图片", Toast.LENGTH_SHORT).show();
            finish();
        }
    }
}

 <activity android:name=".ImageShowActivity"
            android:label="@string/image"
            android:theme="@style/Theme.AppCompat.Light.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <data android:mimeType="image/*" />
            </intent-filter>
        </activity>
