本文实例为大家分享了android实现点击图片全屏展示的具体代码，供大家参考，具体内容如下
MainActivity:
public class MainActivity extends AppCompatActivity {
private ImageView imageView;
private Dialog dialog;
private ImageView image;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
//小图的点击事件（弹出大图）
imageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.show();
}
});
}
private void init() {
imageView = (ImageView) findViewById(R.id.image);
//展示在dialog上面的大图
dialog = new Dialog(MainActivity.this,R.style.FullActivity);
WindowManager.LayoutParams attributes = getWindow().getAttributes();
attributes.width = WindowManager.LayoutParams.MATCH_PARENT;
attributes.height = WindowManager.LayoutParams.MATCH_PARENT;
dialog.getWindow().setAttributes(attributes);
image = getImageView();
dialog.setContentView(image);
//大图的点击事件（点击让他消失）
image.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
}
//动态的ImageView
private ImageView getImageView(){
ImageView imageView = new ImageView(this);
//宽高
imageView.setLayoutParams(new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));
//imageView设置图片
@SuppressLint("ResourceType") InputStream is = getResources().openRawResource(R.drawable.lala);
Drawable drawable = BitmapDrawable.createFromStream(is, null);
imageView.setImageDrawable(drawable);
return imageView;
}
}
布局文件:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> <ImageView android:id="@+id/image" android:src="@drawable/lala" android:layout_centerInParent="true" android:layout_width="200dp" android:layout_height="200dp" /> </LinearLayout>
style:
<style name="FullActivity" parent="AppTheme"> <item name="windowNoTitle">true</item> <item name="android:windowFullscreen">true</item> </style>
效果图:
