我正在做这个项目，我想启动一个应用程序(主 Activity )，并使用 Bottom Sheet 作为说明来了解如何使用某些功能，而主 Activity 在后台打开。
我已经知道如何在 Bottom Sheet 之间转换到另一个 Bottom Sheet ，但我的主要问题是第一个 Bottom Sheet 需要一个按钮本身才能激活，所以我的问题是它可以在应用程序启动时自动完成，而不需要单击 Bottom Sheet 内的按钮后，按钮会消失？
这是我的 Java 代码:
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button buttonShow = findViewById(R.id.button_start);
buttonShow.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final BottomSheetDialog bottomSheetDialog = new BottomSheetDialog(
MainActivity.this, R.style.BottomSheetDesign
);
View bottomSheetView = LayoutInflater.from(getApplicationContext())
.inflate(
R.layout.layout_bottom_sheet,
(LinearLayout)findViewById(R.id.BottomSheetContainer)
);
bottomSheetView.findViewById(R.id.ButtonNext).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final BottomSheetDialog bottomSheetDialog1 = new BottomSheetDialog(
MainActivity.this, R.style.BottomSheetDesign
);
View bottomSheetView1 = LayoutInflater.from(getApplicationContext())
.inflate(
R.layout.layout_bottom_sheet1,
(LinearLayout)findViewById(R.id.BottomSheetContainer1)
);
bottomSheetView1.findViewById(R.id.ButtonDone).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
bottomSheetDialog1.dismiss();
}
});
bottomSheetDialog.dismiss();
bottomSheetDialog1.setContentView(bottomSheetView1);
bottomSheetDialog1.show();
}
});
bottomSheetDialog.setContentView(bottomSheetView);
bottomSheetDialog.show();
}
});
最佳答案
在oncreate方法中直接调用bottomsheet
试试这个代码:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
openBottomSheet();
}
private void openBottomSheet() {
final BottomSheetDialog bottomSheetDialog = new BottomSheetDialog(
MainActivity.this, R.style.BottomSheetDesign
);
View bottomSheetView = LayoutInflater.from(getApplicationContext())
.inflate(
R.layout.layout_bottom_sheet,
(LinearLayout) findViewById(R.id.BottomSheetContainer)
);
bottomSheetView.findViewById(R.id.ButtonNext).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final BottomSheetDialog bottomSheetDialog1 = new BottomSheetDialog(
MainActivity.this, R.style.BottomSheetDesign
);
View bottomSheetView1 = LayoutInflater.from(getApplicationContext())
.inflate(
R.layout.layout_bottom_sheet1,
(LinearLayout) findViewById(R.id.BottomSheetContainer1)
);
bottomSheetView1.findViewById(R.id.ButtonDone).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
bottomSheetDialog1.dismiss();
}
});
bottomSheetDialog.dismiss();
bottomSheetDialog1.setContentView(bottomSheetView1);
bottomSheetDialog1.show();
}
});
bottomSheetDialog.setContentView(bottomSheetView);
bottomSheetDialog.show();
}
关于java - 无需使用按钮即可自动打开 Bottom Sheet ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/61256035/
