从android的自定义活动中删除底部工作表对话

在Chintan Khetiya的回答的帮助下，我创建了一个定制的底层android对话：

我想从BottomDialogue自己的活动中定义的按钮中取消对话，而不是从调用活动中取消对话

以下是我在调用活动中的代码，在调用活动中，我通过单击按钮创建了我的自定义底部工作表\u liab实例：

openBottomDialogeButton.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View view) {
                   **//Creating the BottomDialogue Instance**`Bottomsheet_liab dialog;
    dialog=new Bottomsheet_liab(getActivity());
dialog.getWindow().setBackgroundDrawable(newColorDrawable(Color.TRANSPARENT));`

        }
    });

以下是我在对话活动中的代码：

public class Bottomsheet_liab extends BottomSheetDialog{
@Override
 protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.cashflow_bottomsheet);
         Button btn=(Button)findViewByID(R.id.btnx);
         btn.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View view) {
                   **//I want to dismiss this BottomSheetDialogue from here.How can I do this>**
        }
    });

}

尝试此方法，您需要调用

discouse（）方法，如下面的代码

btn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
      dismiss();
    }
});

示例代码

public class Bottomsheet_liab extends BottomSheetDialog{
@Override
 protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.cashflow_bottomsheet);
         Button btn=(Button)findViewByID(R.id.btnx);
         btn.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View view) {
                   dismiss();
        }
    });

}

private Button startbtn, okaybtn, cancelbtn;
BottomSheetDialog mBottomSheetDialog;
View sheetView;

    mBottomSheetDialog = new BottomSheetDialog(HomeActivity.this);
    sheetView = getLayoutInflater().inflate(R.layout.botomdialouge,null);
    mBottomSheetDialog.setContentView(sheetView);


    okaybtn = sheetView.findViewById(R.id.okaybtn);
    cancelbtn = sheetView.findViewById(R.id.cancelbtn);

   okaybtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            finish();
        }
    });

    cancelbtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mBottomSheetDialog.dismiss();
        }
    });

尝试以下代码

public class Bottomsheet_liab extends BottomSheetDialog{
@Override
 protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.cashflow_bottomsheet);
         Button btn=(Button)findViewByID(R.id.btnx);
         btn.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View view) {
                   dismiss();
        }
    });

}

private Button startbtn, okaybtn, cancelbtn;
BottomSheetDialog mBottomSheetDialog;
View sheetView;

    mBottomSheetDialog = new BottomSheetDialog(HomeActivity.this);
    sheetView = getLayoutInflater().inflate(R.layout.botomdialouge,null);
    mBottomSheetDialog.setContentView(sheetView);


    okaybtn = sheetView.findViewById(R.id.okaybtn);
    cancelbtn = sheetView.findViewById(R.id.cancelbtn);

   okaybtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            finish();
        }
    });

    cancelbtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mBottomSheetDialog.dismiss();
        }
    });

布局代码如下所示

    <LinearLayout
         android:layout_width="match_parent"
         android:layout_height="250dp"
         android:id="@+id/bottomsheet"
         android:clipToPadding="true"
         android:background="@color/colorwhite"

        <ImageView
            android:layout_gravity="center"

            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            />

        <TextView

            android:layout_height="wrap_content"
            android:text="@string/exit"
            android:padding="16dp"/>

        <LinearLayout
            android:orientation="horizontal"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <Button
                android:id="@+id/cancelbtn"
                android:text="Cancel"
                android:textColor="@color/colorwhite"
                android:layout_margin="10dp"
                android:textSize="@dimen/textsizenormal"

                android:layout_margin="10dp"
                android:textSize="@dimen/textsizenormal"
                android:background="@drawable/buttonclick"
                android:layout_weight="1"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />
        </LinearLayout>
    </LinearLayout>
