所以我从一个用于构建图像的屏幕开始。 my build mode 当我点击模板时，我会进入一个看起来像stencil picker的新活动 在我的模板选择器中，我有一个onclick方法用于使用开关盒的图片。我需要做的是记住我点击了什么图像并将该图像应用到上一页。我还需要能够保存添加到构建模式的图像，以便它们可以堆叠在彼此之上（但这是次要问题）。 这是构建页面的代码
public class BuildMode extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener, AdapterView.OnItemSelectedListener {
private Button mStencilButton;
//private Button mColorButton;
private Button mUndoButton;
private Button mRedoButton;
private Spinner mColorSpinner;
private ImageView mImageView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_build_mode);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
//bit map to get stencil selected and place into build mode
// Bundle extras = getIntent().getExtras();
// byte[] byteArray = extras.getByteArray("picture");
// Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
// ImageView image = (ImageView) findViewById(R.id.egg_image);
// image.setImageBitmap(bmp);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
mStencilButton = (Button) findViewById(R.id.stencil_button);
// mColorButton = (Button) findViewById(R.id.color_button);
mUndoButton = (Button) findViewById(R.id.undo_button);
mRedoButton = (Button) findViewById(R.id.redo_button);
mColorSpinner = (Spinner) findViewById(R.id.colors_spinner);
mColorSpinner.setOnItemSelectedListener(this);
mStencilButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(BuildMode.this, StencilList.class);
startActivity(intent);
}
});
mUndoButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
mRedoButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
mColorSpinner = (Spinner) findViewById(R.id.colors_spinner);
mColorSpinner.setOnItemSelectedListener(this);
}
@Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.build_mode, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.about_us) {
return true;
}
return super.onOptionsItemSelected(item);
}
@SuppressWarnings("StatementWithEmptyBody")
@Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_manage_build) {
// Handle the camera action
} else if (id == R.id.nav_gallery_build) {
Intent intent = new Intent(BuildMode.this, PreviewMode.class);
startActivity(intent);
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
switch (position) {
case 0:
// mImageView.setBackgroundColor(Color.WHITE);
break;
case 1:
// mImageView.setBackgroundColor(Color.YELLOW);
break;
case 2:
// mImageView.setBackgroundColor(Color.GREEN);
break;
case 3:
// mImageView.setBackgroundColor(Color.BLUE);
break;
case 4:
// mImageView.setBackgroundColor(Color.RED);
break;
case 5:
// mImageView.setBackgroundColor(Color.BLACK);
break;
}
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
}
和我的模板页面代码
public class StencilList extends AppCompatActivity {
private ImageView mStencil1;
private Bitmap bmp;
private byte[] byteArray;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_stencil_list);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
public void useStencil(View view) {
// Intent intent = new Intent(this, BuildMode.class);
switch (view.getId()) {
case R.id.stencil_image_1:
// intent.putExtra("picture", byteArray);
// startActivity(intent);
break;
case R.id.stencil_image_2:
break;
case R.id.stencil_image_3:
break;
case R.id.stencil_image_4:
break;
case R.id.stencil_image_5:
break;
case R.id.stencil_image_6:
break;
case R.id.stencil_image_7:
break;
case R.id.stencil_image_8:
break;
case R.id.stencil_image_9:
break;
case R.id.stencil_image_10:
break;
case R.id.stencil_image_11:
break;
case R.id.stencil_image_12:
break;
case R.id.stencil_image_13:
break;
case R.id.stencil_image_14:
break;
}
}
private void imageClicked()
{
}
}

我会试试这个：
我希望这有帮助！
