背景:
這幾天做一個復制文本的需求，突然看到QQ上復制昵稱跟QQ號的效果，覺得很不錯，就想要模仿一波，辦法比較簡單粗暴，反編譯QQ獲取了那個.9圖片,然后就是用PopWindow實現了。
解決辦法:
自定義PopWindow
public class CopyContentPopWindow extends PopupWindow {
private final View content;
TextView tvLabel;
TextView tvLabelFake;
Activity context;
private OnCopyContentListener onCopyContentListener;
public CopyContentPopWindow(Activity context) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
content = inflater.inflate(R.layout.popwindow_copy_content, null);
tvLabel = content.findViewById(R.id.tv_label);
tvLabelFake = content.findViewById(R.id.tv_label_fake);
tvLabel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (onCopyContentListener != null) {
onCopyContentListener.copyContent();
}
CopyContentPopWindow.this.dismiss();
}
});
this.setContentView(content);
this.setWidth(ViewGroup.LayoutParams.WRAP_CONTENT);
this.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
this.setFocusable(true);
this.setOutsideTouchable(true);
this.update();
ColorDrawable dw = new ColorDrawable(0000000000);
this.setBackgroundDrawable(dw);
this.context = context;
}
public void setTvLabel(String text) {
tvLabel.setText(text);
tvLabelFake.setText(text);
update();
}
public void setOnCopyContentListener(OnCopyContentListener onCopyContentListener) {
this.onCopyContentListener = onCopyContentListener;
}
public void showPopupWindow(View parent) {
if (!this.isShowing()) {
int[] location = new int[2];
parent.getLocationOnScreen(location);
// this.showAsDropDown(parent, 0, 0);
showAtLocation(parent, Gravity.NO_GRAVITY, location[0], location[1]);
} else {
this.dismiss();
}
}
public interface OnCopyContentListener {
void copyContent();
}
}
具體使用代碼:
public class MainActivity extends AppCompatActivity {
TextView tvNickName;
TextView tvQQNum;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tvNickName = findViewById(R.id.tv_nick_name);
tvQQNum = findViewById(R.id.tv_qq_num);
tvNickName.setOnClickListener(v -> {
CopyContentPopWindow copyContentPopWindow = new CopyContentPopWindow(MainActivity.this);
copyContentPopWindow.setTvLabel("復制");
copyContentPopWindow.setOnCopyContentListener(() -> {
ClipboardManager cm = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
ClipData clipData = ClipData.newPlainText("Label", tvNickName.getText().toString());
cm.setPrimaryClip(clipData);
Toast.makeText(MainActivity.this, "復制成功", Toast.LENGTH_LONG).show();
});
copyContentPopWindow.showPopupWindow(tvNickName);
});
tvQQNum.setOnClickListener(v -> {
CopyContentPopWindow copyContentPopWindow = new CopyContentPopWindow(MainActivity.this);
copyContentPopWindow.setTvLabel("復制QQ號");
copyContentPopWindow.setOnCopyContentListener(() -> {
ClipboardManager cm = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
ClipData clipData = ClipData.newPlainText("Label", "100001");
cm.setPrimaryClip(clipData);
Toast.makeText(MainActivity.this, "復制成功", Toast.LENGTH_LONG).show();
});
copyContentPopWindow.showPopupWindow(tvQQNum);
});
}
}
