如何使用滑塊動畫從左到右打開活動

Question

我想從左向右滑動打開活動...在按鈕上單擊..我創建動畫xml

使用此功能進行意圖類似的滑動動畫

signupbtn.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
            Intent s=new Intent(getApplicationContext(),SignUpActivity.class);


    startActivity(s);
        ((Activity) getApplicationContext()).overridePendingTransition(R.anim.slidleft_to_right,R.anim.slideright_to_left);

                }
            });

但是我的應用程序崩潰了，並在Logcate中給出了錯誤

Answer 1

您不能將ApplicationContext（大多數情況下是Application類）強制轉換為Activity。

只需刪除該部分並留下：

startActivity(s);
overridePendingTransition(R.anim.slidleft_to_right,R.anim.slideright_to_left);

Answer 2

只需將代碼更改為：

signupbtn.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
            Intent s=new Intent(getApplicationContext(),SignUpActivity.class);


            startActivity(s);
         overridePendingTransition(R.anim.slidleft_to_right,R.anim.slideright_to_left);

                }
            });

更新：

對於后壓式：

@Override
public void onBackPressed() {
    super.onBackPressed();
    finish();
    overridePendingTransition(R.anim.slideinfromleft, R.anim.slideouttoright);
}

Answer 3

您需要res / anim.xml從左到右的支持動畫

   <set xmlns:android="http://schemas.android.com/apk/res/android"
        android:shareInterpolator="false">

        <translate android:fromXDelta="-100%" android:toXDelta="0%"
         android:fromYDelta="0%" android:toYDelta="0%"
         android:duration="700"/>

   </set>

.class文件

  this.overridePendingTransition(R.anim.animation_enter, R.anim.animation_leave);
        (OR)
  this.overridePendingTransition(R.anim.slidleft_to_right,R.anim.slideright_to_left);
