activity設定透明並取消跳轉動畫
阿新 • • 發佈：2019-02-15
最近使用activity跳轉取消跳轉動畫，並設定為半透明，使其產生如popupwindow的效果。在這做個記錄程式碼如下：
主activity比較簡單。
package com.huayi.listview; import android.app.Activity; import android.content.Intent; import android.graphics.Bitmap; import android.os.Bundle; import android.text.TextUtils; import android.view.View; import android.widget.ImageView; importandroid.widget.Toast; import com.huayi.listview.utils.BitmapHelper; /** * Created by Administrator on 2016/8/4. */ public class TestTransparentActivity extends Activity { private ImageView imageView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_test_main); imageView = (ImageView) findViewById(R.id.imageView); } public void startTransparentActivity(View view) { Intent intent = new Intent(this, TransparentActivity.class); intent.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION); startActivityForResult(intent, 100); overridePendingTransition(0, 0);//去掉切換動畫關鍵 } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (resultCode == RESULT_OK) { String photoPath = data.getStringExtra("image_path"); if (TextUtils.isEmpty(photoPath)) { toastInfo("這張圖片不可用"); return; } Bitmap bitmap = BitmapHelper.getSmallBitmap(photoPath, true); imageView.setImageBitmap(bitmap); } } private void toastInfo(String msg) { Toast.makeText(this, msg, Toast.LENGTH_SHORT).show(); } }
對應的xml檔案
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <Button android:id="@+id/onclickBtn" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="選擇照片" android:onClick="startTransparentActivity"/> <ImageView android:id="@+id/imageView" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout>
